The function bond_info_query alwarys returns 0. As such, in the function
bond_do_ioctl, it is not necessary to check the returned value. So the
interface type of the function bond_info_query is changed to void. The
redundant check is removed.

Compared to custom busy_poll, the generic NAPI one is simpler and
removes a lot of code. It removes one atomic in the fast path (when
busy poll is not in action) since we do not have to use an extra

Vxlan COLLECT_METADATA mode today solves the per-vni netdev
scalability problem in l3 networks. It expects all forwarding
information to be present in dst_metadata. This patch series
enhances collect metadata mode to include the case where only
vni is present in dst_metadata, and the vxlan driver can then use
the rest of the forwarding information datbase to make forwarding
decisions. There is no change to default COLLECT_METADATA
behaviour. These changes only apply to COLLECT_METADATA when
used with the bridging use-case with a special dst_metadata
tunnel info flag (eg: where vxlan device is part of a bridge).
For all this to work, the vxlan driver will need to now support a
single fdb table hashed by mac + vni. This series essentially makes
this happen.
use-case and workflow:
vxlan collect metadata device participates in bridging vlan
to vn-segments. Bridge driver above the vxlan device,
sends the vni corresponding to the vlan in the dst_metadata.
vxlan driver will lookup forwarding database with (mac + vni)
for the required remote destination information to forward the
packet.
Changes introduced by this patch:
- allow learning and forwarding database state in vxlan netdev in
COLLECT_METADATA mode. Current behaviour is not changed
by default. tunnel info flag IP_TUNNEL_INFO_BRIDGE is used
to support the new bridge friendly mode.
- A single fdb table hashed by (mac, vni) to allow fdb entries with
multiple vnis in the same fdb table
- rx path already has the vni
- tx path expects a vni in the packet with dst_metadata
- prior to this series, fdb remote_dsts carried remote vni and
the vxlan device carrying the fdb table represented the
source vni. With the vxlan device now representing multiple vnis,
this patch adds a src vni attribute to the fdb entry. The remote
vni already uses NDA_VNI attribute. This patch introduces
NDA_SRC_VNI netlink attribute to represent the src vni in a multi
vni fdb table.
iproute2 example (patched and pruned iproute2 output to just show
relevant fdb entries):
example shows same host mac learnt on two vni's.
before (netdev per vni):
$bridge fdb show | grep "00:02:00:00:00:03"
00:02:00:00:00:03 dev vxlan1001 dst 12.0.0.8 self
00:02:00:00:00:03 dev vxlan1000 dst 12.0.0.8 self
after this patch with collect metadata in bridged mode (single netdev):
$bridge fdb show | grep "00:02:00:00:00:03"

The firmware will soon actually look at the AID field, and
when it does that it'll try to ensure that the AID is never
changing. Due to the way the station is added, it may start
with an invalid AID before it's associated, so to ensure a
constant AID (once it becomes non-zero), track the station
state and set the AID only when the station is associated
and when it disassociates.

This fixes a long-standing bug that was introduced when this code
was introduced: cfg80211 passes a pointer, but we treat it as if
it was passing a value. The result is that we pass the pointer to
the firmware, instead of the value. It's not clear how this could
ever have worked, unless the firmware is ignoring this value.

When driver needs to access the contents of a streaming DMA buffer
without unmapping it it should call dma_sync_single_for_cpu().
Once the call has been made, the CPU "owns" the DMA buffer and can
work with it as needed.
Before the device accesses the buffer, however, ownership should be
transferred back to it with dma_sync_single_for_device().
Both calls weren't performed by the driver, resulting with odd paging
errors on some platforms. Fix it.

For a000 devices the INIT and RT images are unified to one
image.
The changes in the flow are the following:
* Driver load only RT firmware - meaning that the nvm access
command will be done in the RT image load flow.
* A new command (NVM_ACCESS_COMPLETE) now signals to the FW that
the driver is done accessing the NVM and FW can proceed with phy
calibrations.
* Phy DB is no longer sent from INIT FW to be restored by driver
for the RT FW - all the phy DB is now internal to the FW.
INIT complete will now follow the NVM access command, without
phy DB calls before.
* Paging command is sent earlier in the flow before NVM access
to enable a complete load of FW.
* caution must be care when restart is called since we may have
not completed init flow even though we are in RT firmware.

Due to the resolution of the register controlling interrupt rate
limiting, setting certain values for the interrupt rate limit make it
appear as though the limiting is not completely accurate. The problem
is that the interrupt rate limit is getting rounded down to the nearest
multiple of 4. This patch fixes the problem by adding some feedback to
the user as to the actual interrupt rate limit being used when it
differs from the requested limit. Without this patch setting interrupt
rate limits may appear to behave inaccurately.

This patch refactors the macro INTRL_USEC_TO_REG into a static inline
function and fixes a couple subtle bugs caused by the macro.
This patch fixes a bug which was caused by passing a bad register value
to the firmware. If enabling interrupt rate limiting, a non-zero value
for the rate limit must be used. Otherwise the firmware sets the
interrupt rate limit to the maximum value. Due to the limited
resolution of the register, attempting to set a value of 1, 2, or 3
would be rounded down to 0 and limiting was left enabled, causing
unexpected behavior.
This patch also fixes a possible bug in which using the macro itself can
introduce unintended side-affects because the macro argument is used
more than once in the macro definition (e.g. a variable post-increment
argument would perform a double increment on the variable).
Without this patch, attempting to set interrupt rate limits of 1, 2, or
3 results in unexpected behavior and future use of this macro could
cause subtle bugs.

'struct i40e_dma_mem' defined with 'packed' directive causing kernel

i40e 0000:03:00.0: fw 5.1.40981 api 1.5 nvm 5.04 0x80002548 0.0.0
This can be fixed with get_unaligned/put_unaligned(). However no
reference in driver shows that 'struct i40e_dma_mem' directly shoved
into NIC hardware. But instead fields of the struct are being read and
used for hardware. Therefore, __packed is unnecessary for 'struct
i40e_dma_mem'.
In addition, although 'struct i40e_virt_mem' doesn't cause any
unaligned access, keeping it packed is unnecessary as well because
of aforementioned reason.
This change make 'struct i40e_dma_mem' and 'struct i40e_virt_mem'
unpacked.

Instead of using i40e_add_filter or i40e_del_filter directly, when

of VLAN mode or PVID settings. This ensures consistency and avoids the
issues that can occur with the recent addition of a WARN_ON() in

only have I40E_VLAN_ANY filters. The new names convey how they function

This function won't be appreciably slower when in VLAN mode, so there is
no real reason to not just call it directly. In either case, we still
must search the full table for a MAC/VLAN pair. We do get to stop
searching a tiny bit early in the case of knowing we are not in VLAN
mode, but this is a minor savings and we can avoid the code complexity
by not having to worry about the check.

Now that we have the separate i40e_(add|rm)_vlan_all_mac functions, we
should not be using the i40e_vsi_kill_vlan or i40e_vsi_add_vlan
functions when PVID is set or when VID is less than 1. This allows us to
remove some checks in i40e_vsi_add_vlan and ensures that callers which
need to handle VID=0 or VID=-1 don't accidentally invoke the VLAN mode
handling used to convert filters when entering VLAN mode. We also update
the functions to take u16 instead of s16 as well since they no longer
expect to be called with VID=I40E_VLAN_ANY.

Keep references on the PHY driver module right before we are going to
utilize it in phy_attach_direct(), and conversely when we don't use it
anymore in phy_detach().

In order to enable 2.5Gbps mode, we need the base speed of 10G, plus
the Alt bit setting. Fix a typ0 that used 1Gb base speed.

Chips like Amlogic S905GXBB are supported by this driver but don't
have support for PTP. Add a separate warning for missing HW support
to differentiate it from other actual failures.

The mv88e6390 Ethernet switch has internal PHYs. These PHYs don't have
an model ID in the ID2 register. So the MDIO driver in the switch
intercepts reads to this register, and returns the switch family ID.
Extend the Marvell PHY driver by including this ID, and treat the PHY
as a 88E1540.

The internal PHYs of the mv88e6390 do not have a model ID. Trap any
calls to the ID register, and if it is zero, return the ID for the
mv88e6390. The Marvell PHY driver can then bind to this ID.
