If an aggregate has the following conditions:
- The SRIOV LAG DDP package has been enabled
- The bond is in 802.3ad LACP mode
- The bond is disqualified from supporting SRIOV VF LAG
- Both interfaces were added simultaneously to the bond (same command)
Then there is a chance that the two interfaces will be assigned different
LACP Aggregator ID's. This will cause a failure of the LACP control over
the bond.
To fix this, we can detect if the primary interface for the bond (as
defined by the driver) is not in switchdev mode, and exit the setup flow
if so.
Reproduction steps:
%> ip link add bond0 type bond mode 802.3ad miimon 100
%> ip link set bond0 up
%> ifenslave bond0 eth0 eth1
%> cat /proc/net/bonding/bond0 | grep Agg
Check for Aggregator IDs that differ.

The ice_vc_repr_add_mac() function indicates that it does not store the MAC
address filters in the firmware. However, it still increments vf->num_mac.
This is incorrect, as vf->num_mac should represent the number of MAC
filters currently programmed to firmware.
Indeed, we only perform this increment if the requested filter is a unicast
address that doesn't match the existing vf->hw_lan_addr. In addition,
ice_vc_repr_del_mac() does not decrement the vf->num_mac counter. This
results in the counter becoming out of sync with the actual count.
As it turns out, vf->num_mac is currently only used in legacy made without
port representors. The single place where the value is checked is for
enforcing a filter limit on untrusted VFs.
Upcoming patches to support VF Live Migration will use this value when
determining the size of the TLV for MAC address filters. Fix the
representor mode function to stop incrementing the counter incorrectly.

====================
Prepare for Intel IPU E2000 (GEN3)
This is the first part in introducing RDMA support for idpf.
----------------------------------------------------------------
Tatyana Nikolova says:
To align with review comments, the patch series introducing RDMA
RoCEv2 support for the Intel Infrastructure Processing Unit (IPU)
E2000 line of products is going to be submitted in three parts:
1. Modify ice to use specific and common IIDC definitions and
pass a core device info to irdma.
2. Add RDMA support to idpf and modify idpf to use specific and
common IIDC definitions and pass a core device info to irdma.
3. Add RDMA RoCEv2 support for the E2000 products, referred to as
GEN3 to irdma.
This first part is a 5 patch series based on the original
"iidc/ice/irdma: Update IDC to support multiple consumers" patch
to allow for multiple CORE PCI drivers, using the auxbus.
Patches:
1) Move header file to new name for clarity and replace ice
specific DSCP define with a kernel equivalent one in irdma
2) Unify naming convention
3) Separate header file into common and driver specific info
4) Replace ice specific DSCP define with a kernel equivalent
one in ice
5) Implement core device info struct and update drivers to use it

In preparation of supporting more than a single core PCI driver
for RDMA, move ice specific structs like qset_params, qos_info
and qos_params from iidc_rdma.h to iidc_rdma_ice.h.
Previously, the ice driver was just exporting its entire PF struct
to the auxiliary driver, but since each core driver will have its own
different PF struct, implement a universal struct that all core drivers
can provide to the auxiliary driver through the probe call.

Use Device Serial Number instead of PCI bus/device/function for
the index of struct ice_adapter.
Functions on the same physical device should point to the very same
ice_adapter instance, but with two PFs, when at least one of them is
PCI-e passed-through to a VM, it is no longer the case - PFs will get
seemingly random PCI BDF values, and thus indices, what finally leds to
each of them being on their own instance of ice_adapter. That causes them
to don't attempt any synchronization of the PTP HW clock usage, or any
other future resources.
DSN works nicely in place of the index, as it is "immutable" in terms of
virtualization.

The Get Tx Topology AQ command (opcode 0x0418) has different read flag
requirements depending on the hardware/firmware. For E810, E822, and E823
firmware the read flag must be set, and for newer hardware (E825 and E830)
it must not be set.
This results in failure to configure Tx topology and the following warning
message during probe:
DDP package does not support Tx scheduling layers switching feature -
please update to the latest DDP package and try again
The current implementation only handles E825-C but not E830. It is
confusing as we first check ice_is_e825c() and then set the flag in the set
case. Finally, we check ice_is_e825c() again and set the flag for all other
hardware in both the set and get case.
Instead, notice that we always need the read flag for set, but only need
the read flag for get on E810, E822, and E823 firmware. Fix the logic to
check the MAC type and set the read flag in get only on the older devices
which require it.

The PTP_PEROUT_REQUEST2 ioctl has gained support for flags specifying
specific output behavior including PTP_PEROUT_ONE_SHOT,
PTP_PEROUT_DUTY_CYCLE, PTP_PEROUT_PHASE.
Driver authors are notorious for not checking the flags of the request.
This results in misinterpreting the request, generating an output signal
that does not match the requested value. It is anticipated that even more
flags will be added in the future, resulting in even more broken requests.
Expecting these issues to be caught during review or playing whack-a-mole
after the fact is not a great solution.
Instead, introduce the supported_perout_flags field in the ptp_clock_info
structure. Update the core character device logic to explicitly reject any
request which has a flag not on this list.
This ensures that drivers must 'opt in' to the flags they support. Drivers
which don't set the .supported_perout_flags field will not need to check
that unsupported flags aren't passed, as the core takes care of this.
Update the drivers which do support flags to set this new field.
Note the following driver files set n_per_out to a non-zero value but did
not check the flags at all:
• drivers/ptp/ptp_clockmatrix.c
• drivers/ptp/ptp_idt82p33.c

The PTP_EXTTS_REQUEST(2) ioctl has a flags field which specifies how the
external timestamp request should behave. This includes which edge of the
signal to timestamp, as well as a specialized "offset" mode. It is expected
that more flags will be added in the future.
Driver authors routinely do not check the flags, often accepting requests
with flags which they do not support. Even drivers which do check flags may
not be future-proofed to reject flags not yet defined. Thus, any future
flag additions often require manually updating drivers to reject these
flags.
This approach of hoping we catch flag checks during review, or playing
whack-a-mole after the fact is the wrong approach.
Introduce the "supported_extts_flags" field to the ptp_clock_info
structure. This field defines the set of flags the device actually
supports.
Update the core character device logic to check this field and reject
unsupported requests. Getting this right is somewhat tricky. First, to
avoid unnecessary repetition and make basic functionality work when
.supported_extts_flags is 0, the core always accepts the PTP_ENABLE_FEATURE
flag. This flag is used to set the 'on' parameter to the .enable function
and is thus always 'supported' by all drivers.
For backwards compatibility, the PTP_RISING_EDGE and PTP_FALLING_EDGE flags
are merely "hints" when using the old PTP_EXTTS_REQUEST ioctl, and are not
expected to be enforced. If the user issues PTP_EXTTS_REQUEST2, the
PTP_STRICT_FLAGS flag is added which is supposed to inform the driver to
strictly validate the flags and reject unsupported requests. To handle
this, first check if the driver reports PTP_STRICT_FLAGS support. If it
does not, then always allow the PTP_RISING_EDGE and PTP_FALLING_EDGE flags.
This keeps backwards compatibility with the original PTP_EXTTS_REQUEST
ioctl where these flags are not guaranteed to be honored.
This way, drivers which do not set the supported_extts_flags will continue
to accept requests for the original PTP_EXTTS_REQUEST ioctl. The core will
automatically reject requests with new flags, and correctly reject requests
with PTP_STRICT_FLAGS, where the driver is supposed to strictly validate
the flags.
Update the various drivers, refactoring their validation logic into the
.supported_extts_flags field. For consistency and readability,
PTP_ENABLE_FEATURE is not set in the supported flags list, and
PTP_EXTTS_EDGES is expanded to PTP_RISING_EDGE | PTP_FALLING_EDGE in all
cases.
Note the following driver files set n_ext_ts to a non-zero value but did
not check flags at all:
• drivers/net/ethernet/freescale/dpaa2/dpaa2-ptp.c
• drivers/net/ethernet/freescale/enetc/enetc_ptp.c
• drivers/net/ethernet/intel/i40e/i40e_ptp.c
• drivers/net/ethernet/marvell/octeontx2/nic/otx2_ptp.c
• drivers/net/ethernet/renesas/ravb_ptp.c
• drivers/net/ethernet/renesas/rtsn.c
• drivers/net/ethernet/renesas/rtsn.h
• drivers/net/ethernet/ti/am65-cpts.c
• drivers/net/ethernet/ti/cpts.h
• drivers/net/ethernet/ti/icssg/icss_iep.c
• drivers/net/ethernet/xscale/ptp_ixp46x.c
• drivers/net/phy/bcm-phy-ptp.c
• drivers/ptp/ptp_ocp.c
• drivers/ptp/ptp_pch.c
• drivers/ptp/ptp_qoriq.c
These drivers behavior does change slightly: they will now reject the
PTP_EXTTS_REQUEST2 ioctl, because they do not strictly validate their
flags. This also makes them no longer incorrectly accept PTP_EXT_OFFSET.
Also note that the renesas ravb driver does not support PTP_STRICT_FLAGS.
We could leave the .supported_extts_flags as 0, but I added the
PTP_RISING_EDGE | PTP_FALLING_EDGE since the driver previously manually
validated these flags. This is equivalent to 0 because the core will allow
these flags regardless unless PTP_STRICT_FLAGS is also set.

According to the E825C specification, SBQ address for ports on a single
complex is device 2 for PHY 0 and device 13 for PHY1.
For accessing ports on a dual complex E825C (so called 2xNAC mode),
the driver should use destination device 2 (referred as phy_0) for
the current complex PHY and device 13 (referred as phy_0_peer) for
peer complex PHY.
Differentiate SBQ destination device by checking if current PF port
number is on the same PHY as target port number.
Adjust 'ice_get_lane_number' function to provide unique port number for
ports from PHY1 in 'dual' mode config (by adding fixed offset for PHY1
ports). Cache this value in ice_hw struct.
Introduce ice_get_primary_hw wrapper to get access to timesync register

Due to the bug in FW/NVM autoload mechanism (wrong default
SB_REM_DEV_CTL register settings), the access to peer PHY and CGU
clients was disabled by default.
As the workaround solution, the register value was overwritten by the
driver at the probe or reset handling.
Remove workaround as it's not needed anymore. The fix in autoload
procedure has been provided with NVM 3.80 version.
NOTE: at the time the fix was provided in NVM, the E825C product was
not officially available on the market, so it's not expected this change
will cause regression when running with older driver/kernel versions.

Only a single VSI can be in charge of sending LLDP frames, sometimes it is
beneficial to assign this function to a VF, that is possible to do with tc
capabilities in the switchdev mode. It requires first blocking the PF from
sending the LLDP frames with a following command:
tc filter add dev <ifname> egress protocol lldp flower skip_sw action drop
Then it becomes possible to configure a forward rule from a VF port
representor to uplink instead.
tc filter add dev <vf_ifname> ingress protocol lldp flower skip_sw
action mirred egress redirect dev <ifname>
How LLDP exclusivity was done previously is LLDP traffic was blocked for a
whole port by a single rule and PF was bypassing that. Now at least in the
switchdev mode, every separate VSI has to have its own drop rule. Another
complication is the fact that tc does not respect when the driver refuses
to delete a rule, so returning an error results in a HW rule still present
with no way to reference it through tc. This is addressed by allowing the
PF rule to be deleted at any time, but making the VF forward rule "dormant"
in such case, this means it is deleted from HW but stays in tc and driver's
bookkeeping to be restored when drop rule is added back to the PF.
Implement tc configuration handling which enables the user to transmit LLDP
packets from VF instead of PF.

tc clsact qdisc allows us to add offloaded egress rules with commands such
as the following one:
tc filter add dev <ifname> egress protocol lldp flower skip_sw action drop
Support the egress rule drop action when added to PF, with a few caveats:
* in switchdev mode, all PF traffic has to go uplink with an exception for
LLDP that can be delegated to a single VSI at a time
* in legacy mode, we cannot delegate LLDP functionality to another VSI, so
such packets from PF should not be blocked.
Also, simplify the rule direction logic, it was previously derived from
actions, but actually can be inherited from the tc block (and flipped in
case of port representors).

When a trusted VF tries to configure an LLDP multicast address, configure a
rule that would mirror the traffic to this VF, untrusted VFs are not
allowed to receive LLDP at all, so the request to add LLDP MAC address will
always fail for them.
Add a forwarding LLDP filter to a trusted VF when it tries to add an LLDP
multicast MAC address. The MAC address has to be added after enabling
trust (through restarting the LLDP service).

Commit 34295a3696fb ("ice: implement new LLDP filter command")
introduced the ability to use LLDP-specific filter that directs all
LLDP traffic to a single VSI. However, current goal is for all trusted VFs
to be able to see LLDP neighbors, which is impossible to do with the
special filter.
Make using the generic filter the default choice and fall back to special
one only if a generic filter cannot be added. That way setups with "NVMs
where an already existent LLDP filter is blocking the creation of a filter
to allow LLDP packets" will still be able to configure software Rx LLDP on
PF only, while all other setups would be able to forward them to VFs too.

In case the rule already exists and another VSI wants to subscribe to it
new VSI list is being created and both VSIs are moved to it.
Currently, the check for already existing VSI with the same rule is done
based on fdw_id.hw_vsi_id, which applies only to LOOKUP_RX flag.
Change it to vsi_handle. This is software VSI ID, but it can be applied
here, because vsi_map itself is also based on it.
Additionally change return status in case the VSI already exists in the
VSI map to "Already exists". Such case should be handled by the caller.

If the CONFIG_INFINIBAND_IRDMA symbol is not enabled as a module or a
built-in, then don't let the driver reserve resources for RDMA. The result
of this change is a large savings in resources for older kernels, and a
cleaner driver configuration for the IRDMA=n case for old and new kernels.
Implement this by avoiding enabling the RDMA capability when scanning
hardware capabilities.
Note: Loading the out-of-tree irdma driver in connection to the in-kernel
ice driver, is not supported, and should not be attempted, especially when
disabling IRDMA in the kernel config.

On E800 series hardware, if the start time for a periodic output signal is
programmed into GLTSYN_TGT_H and GLTSYN_TGT_L registers, the hardware logic
locks up and the periodic output signal never starts. Any future attempt to
reprogram the clock function is futile as the hardware will not reset until
a power on.
The ice_ptp_cfg_perout function has logic to prevent this, as it checks if
the requested start time is in the past. If so, a new start time is
calculated by rounding up.
Since commit d755a7e129a5 ("ice: Cache perout/extts requests and check
flags"), the rounding is done to the nearest multiple of the clock period,
rather than to a full second. This is more accurate, since it ensures the
signal matches the user request precisely.
Unfortunately, there is a race condition with this rounding logic. If the
current time is close to the multiple of the period, we could calculate a
target time that is extremely soon. It takes time for the software to
program the registers, during which time this requested start time could
become a start time in the past. If that happens, the periodic output
signal will lock up.
For large enough periods, or for the logic prior to the mentioned commit,
this is unlikely. However, with the new logic rounding to the period and
with a small enough period, this becomes inevitable.
For example, attempting to enable a 10MHz signal requires a period of 100
nanoseconds. This means in the *best* case, we have 99 nanoseconds to
program the clock output. This is essentially impossible, and thus such a
small period practically guarantees that the clock output function will
lock up.
To fix this, add some slop to the clock time used to check if the start
time is in the past. Because it is not critical that output signals start
immediately, but it *is* critical that we do not brick the function, 0.5
seconds is selected. This does mean that any requested output will be
delayed by at least 0.5 seconds.
This slop is applied before rounding, so that we always round up to the
nearest multiple of the period that is at least 0.5 seconds in the future,
ensuring a minimum of 0.5 seconds to program the clock output registers.
Finally, to ensure that the hardware registers programming the clock output
complete in a timely manner, add a write flush to the end of
ice_ptp_write_perout. This ensures we don't risk any issue with PCIe
transaction batching.
Strictly speaking, this fixes a race condition all the way back at the
initial implementation of periodic output programming, as it is
theoretically possible to trigger this bug even on the old logic when
always rounding to a full second. However, the window is narrow, and the
code has been refactored heavily since then, making a direct backport not
apply cleanly.

E830 supports raw receive and generic transmit checksum offloads.
Raw receive checksum support is provided by hardware calculating the
checksum over the whole packet, regardless of type. The calculated
checksum is provided to driver in the Rx flex descriptor. Then the driver
assigns the checksum to skb->csum and sets skb->ip_summed to
CHECKSUM_COMPLETE.
Generic transmit checksum support is provided by hardware calculating the
checksum given two offsets: the start offset to begin checksum calculation,
and the offset to insert the calculated checksum in the packet. Support is
advertised to the stack using NETIF_F_HW_CSUM feature.
E830 has the following limitations when both generic transmit checksum
offload and TCP Segmentation Offload (TSO) are enabled:
1. Inner packet header modification is not supported. This restriction
includes the inability to alter TCP flags, such as the push flag. As a
result, this limitation can impact the receiver's ability to coalesce
packets, potentially degrading network throughput.
2. The Maximum Segment Size (MSS) is limited to 1023 bytes, which prevents
support of Maximum Transmission Unit (MTU) greater than 1063 bytes.
Therefore NETIF_F_HW_CSUM and NETIF_F_ALL_TSO features are mutually
exclusive. NETIF_F_HW_CSUM hardware feature support is indicated but is not
enabled by default. Instead, IP checksums and NETIF_F_ALL_TSO are the
defaults. Enforcement of mutual exclusivity of NETIF_F_HW_CSUM and
NETIF_F_ALL_TSO is done in ice_set_features(). Mutual exclusivity
of IP checksums and NETIF_F_HW_CSUM is handled by netdev_fix_features().
When NETIF_F_HW_CSUM is requested the provided skb->csum_start and
skb->csum_offset are passed to hardware in the Tx context descriptor
generic checksum (GCS) parameters. Hardware calculates the 1's complement
from skb->csum_start to the end of the packet, and inserts the result in
the packet at skb->csum_offset.

Ever since removing switchdev control VSI and using PF for port
representor Tx/Rx, switchdev slow-path has been working improperly after
failover in SR-IOV LAG. LAG assumes that the first uplink to be added to
the aggregate will own VFs and have switchdev configured. After
failing-over to the other uplink, representors are still configured to
Tx through the uplink they are set up on, which fails because that
uplink is now down.
On failover, update all PRs on primary uplink to use the currently
active uplink for Tx. Call netif_keep_dst(), as the secondary uplink
might not be in switchdev mode. Also make sure to call
ice_eswitch_set_target_vsi() if uplink is in LAG.
On the Rx path, representors are already working properly, because
default Tx from VFs is set to PF owning the eswitch. After failover the
same PF is receiving traffic from VFs, even though link is down.

Fix aRFS (accelerated Receive Flow Steering) structures memory leak by
adding a checker to verify if aRFS memory is already allocated while
configuring VSI. aRFS objects are allocated in two cases:
- as part of VSI initialization (at probe), and
- as part of reset handling
However, VSI reconfiguration executed during reset involves memory
allocation one more time, without prior releasing already allocated

After switchdev is enabled and disabled later, LLDP packets sending stops,
despite working perfectly fine before and during switchdev state.
To reproduce (creating/destroying VF is what triggers the reconfiguration):
devlink dev eswitch set pci/<address> mode switchdev
echo '2' > /sys/class/net/<ifname>/device/sriov_numvfs
echo '0' > /sys/class/net/<ifname>/device/sriov_numvfs
This happens because LLDP relies on the destination override functionality.
It needs to 1) set a flag in the descriptor, 2) set the VSI permission to
make it valid. The permissions are set when the PF VSI is first configured,
but switchdev then enables it for the uplink VSI (which is always the PF)
once more when configured and disables when deconfigured, which leads to
software-generated LLDP packets being blocked.
Do not modify the destination override permissions when configuring
switchdev, as the enabled state is the default configuration that is never
modified.

Delete the driver CPU affinity and aRFS rmap info, use the core's
API instead.

As part of switchdev environment setup, uplink VSI is configured as
default for both Tx and Rx. Default Rx VSI is also used by promiscuous
mode. If promisc mode is enabled and an attempt to enter switchdev mode
is made, the setup will fail because Rx VSI is already configured as
default (rule exists).
Reproducer:
devlink dev eswitch set $PF1_PCI mode switchdev
ip l s $PF1 up
ip l s $PF1 promisc on
echo 1 > /sys/class/net/$PF1/device/sriov_numvfs
In switchdev setup, use ice_set_dflt_vsi() instead of plain
ice_cfg_dflt_vsi(), which avoids repeating setting default VSI for Rx if
it's already configured.
Fixes: 50d62022f455 ("ice: default Tx rule instead of to queue")
