100GbE Intel Wired LAN Driver Updates 2022-07-28
This series contains updates to ice driver only.
Michal allows for VF true promiscuous mode to be set for multiple VFs
and adds clearing of promiscuous filters when VF trust is removed.
Maciej refactors ice_set_features() to track/check changed features
instead of constantly checking against netdev features and adds support for
NETIF_F_LOOPBACK.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
ice: allow toggling loopback mode via ndo_set_features callback
ice: compress branches in ice_set_features()
ice: Fix promiscuous mode not turning off
ice: Introduce enabling promiscuous mode on multiple VF's

Representors do not want to be subject to the PF's Ethernet address
filters, since traffic from VFs will typically have a destination
either elsewhere on the link segment or on an overlay network.
So, create a dynamic m-port with promiscuous and all-multicast
filters, and set it as the egress port of representor default rules.
Since the m-port is an alias of the calling PF's own m-port, traffic
will still be delivered to the PF's RXQs, but it will be subject to
the VNRX filter rules installed on the dynamic m-port (specified by
the v-port ID field of the filter spec).

We need to be able to drop the efx->filter_sem in ef100_filter_table_up()
so that we can call functions that insert filters (and thus take that
rwsem for read), which means the efx->type->filter_table_probe method
needs to be responsible for taking the lock in the first place.

Default rules are low-priority switching rules which the hardware uses
in the absence of higher-priority rules. Each representor requires a
corresponding rule matching traffic from its representee VF and
delivering to the PF (where a check on INGRESS_MPORT in
__ef100_rx_packet() will direct it to the representor). No rule is
required in the reverse direction, because representor TX uses a TX
override descriptor to bypass the MAE and deliver directly to the VF.
Since inserting any rule into the MAE disables the firmware's own
default rules, also insert a pair of rules to connect the PF to the
physical network port and vice-versa.

Traffic delivered to the (MAE admin) PF could be from either the wire
or a VF. The INGRESS_MPORT field of the RX prefix distinguishes these;
base_mport is the value this field will have for traffic from the wire
(which should be delivered to the PF's netdevice, not a representor).

Representor RX uses a NAPI context driven by a 'fake interrupt': when
the parent PF receives a packet destined for the representor, it adds
it to an SKB list (efv->rx_list), and schedules NAPI if the 'fake
interrupt' is primed. The NAPI poll then pulls packets off this list
and feeds them to the stack with netif_receive_skb_list().
This scheme allows us to decouple representor RX from the parent PF's
RX fast-path.
This patch implements the 'top half', which builds an SKB, copies data
into it from the RX buffer (which can then be released), adds it to
the queue and fires the 'fake interrupt' if necessary.

The naming of the get/set/clear firmware feature capability bits doesn't
really follow the established namespace pattern of
wcn36xx_logicalblock_do_something();
The feature bits are accessed by smd.c and main.c. It would be nice to
display the found feature bits in debugfs. To do so though we should tidy
up the namespace a bit.
Move the firmware feature exchange API to its own file - firmware.c giving
us the opportunity to functionally decompose other firmware related
accessors as appropriate in future.

The 'get_ts_info' callback is used for obtaining information about
time stamping and PTP hardware clock capabilities of a network device.
The existing function of Spectrum-1 is used to advertise the PHC
capabilities and the supported RX and TX filters. Implement a similar
function for Spectrum-2, expose that the supported 'rx_filters' are all
PTP event packets, as for these packets the driver fills the time stamp
from the CQE in the SKB.
In the future, mlxsw driver will be extended to support one-step PTP in
Spectrum-2 and newer ASICs. Then additional 'tx_types' will be supported.

The SIOCSHWTSTAMP ioctl configures HW timestamping on a given port. In
Spectrum-2 and above, each packet gets time stamp by default, but in
order to provide an accurate time stamp, software should configure to
update the correction field. In addition, the PTP traps are not enabled
by default, software should enable it per port or for all ports.
The switch behaves like a transparent clock between CPU port and each
front panel port. If ingress correction is set on a port for a given packet
type, then when such a packet is received via the port, the current time
stamp is subtracted from the correction field. If egress correction is set
on a port for a given packet type, then when such a packet is transmitted
via the port, the current time stamp is added to the correction field.
The result is that as the packet ingresses through a port with ingress
correction enabled, and egresses through a port with egress correction
enabled, the PTP correction field is updated to reflect the time that the
packet spent in the ASIC.
This can be used to update the correction field of trapped packets by
enabling ingress correction on a port where time stamping was enabled,
and egress correction on the CPU port. Similarly, for packets transmitted
from the host, ingress correction should be enabled on the CPU port, and
egress correction on a front-panel port.
However, since the correction fields will be updated for all PTP packets
crossing the CPU port, in order not to mangle the correction field, the
front panel port involved in the packet transfer must have the
corresponding correction enabled as well.
Therefore, when HW timestamping is enabled on at least one port, we have
to configure hardware to update the correction field and trap PTP event
packets on all ports.
Add reference count as part of 'struct mlxsw_sp_ptp_state', to maintain
how many ports use HW timestamping. Handle the correction field
configuration only when the first port enables time stamping and when the
last port disables time stamping. Store the configuration as part of
'struct mlxsw_sp_ptp_state', as it is global for all ports.
The SIOCGHWTSTAMP ioctl is a getter for the current configuration,
implement it and use the global configuration.

As opposed to Spectrum-1, in which time stamps arrive through a pair of
dedicated events into a queue and later are being matched to the
corresponding packets, in Spectrum-2 we are reading the time stamps
directly from the CQE. Software can get the time stamp in UTC format
using CQEv2.
Add a time stamp field to 'struct mlxsw_skb_cb'. In
mlxsw_pci_cqe_{rdq,sdq}_handle() extract the time stamp from the CQE into
the new time stamp field. Note that the time stamp in the CQE is
represented by 38 bits, which is a short representation of UTC time.
Software should create the full time stamp using the global UTC clock.
Read UTC clock from hardware only for PTP packets which were trapped to CPU
with PTP0 trap ID (event packets).
Use the time stamp from the SKB when packet is received or transmitted.

In Spectrum-2 and Spectrum-3, the correction field of PTP packets which are
sent as control packets is not updated at egress port. To overcome this
limitation, PTP packets which require time stamp, should be sent as data
packets with the following details:
1. FID valid = 1
2. FID value above the maximum FID
3. rx_router_port = 1
>From Spectrum-4 and on, this limitation will be solved.
Extend the function which handles TX header, in case that the packet is
a PTP packet, add TX header with type=data and all the above mentioned
requirements. Add operation as part of 'struct mlxsw_sp_ptp_ops', to be
able to separate the handling of PTP packets between different ASICs. Use
the data packet solution only for Spectrum-2 and Spectrum-3. Therefore, add
a dedicated operation structure for Spectrum-4, as it will be same to
Spectrum-2 in PTP implementation, just will not have the limitation of

Lay the groundwork for Spectrum-2 support. On Spectrum-2, the packets get
the time stamps from the CQE, which means that the time stamp is attached
to its packet.
Configure MTPTPT to set which message types should arrive under which
PTP trap. PTP0 will be used for event message types, which means that
the packets require time stamp. PTP1 will be used for other packets.
Note that in Spectrum-2, all packets contain time stamp by default. The two
types of traps (PTP0, PTP1) will be used to separate between PTP_EVENT
traps and PTP_GENERAL traps, so then the driver will fill the time stamp as
part of the SKB only for event message types.
Later the driver will enable the traps using 'MTPCPC.ptp_trap_en' bit.
Then, PTP packets start arriving through the PTP traps.
Currently, the structure 'mlxsw_sp2_ptp_state' contains only the common
structure, the next patches will extend it.

Currently, Tx completions are reported using Completion Queue Element

which is fine as Spectrum-1 reads Tx time stamps via a dedicated FIFO
and Spectrum-2 does not currently support PTP.
