Add support for configuring the learning state of a switch port.
When the user requests the HW learning to be disabled, a fast-age
procedure on that specific port is run so that previously learnt
addresses do not linger.
At device probe as well as on a bridge leave action, the ports are
configured with HW learning disabled since they are basically a
standalone port.
At the same time, at bridge join we inherit the bridge port BR_LEARNING
flag state and configure it on the switch port.
There were already some MC firmware ABI functions for changing the
learning state, but those were per FDB (bridging domain) and not per
port so we need to adjust those to use the new MC fw command which is

100GbE Intel Wired LAN Driver Updates 2021-03-22
This series contains updates to ice and iavf drivers.
Haiyue Wang says:
The Intel E810 Series supports a programmable pipeline for a domain
specific protocols classification, for example GTP by Dynamic Device
Personalization (DDP) profile.
The E810 PF has introduced flex-bytes support by ethtool user-def option
allowing for packet deeper matching based on an offset and value for DDP
usage.
For making VF also benefit from this flexible protocol classification,
some new virtchnl messages are defined and handled by PF, so VF can
query this new flow director capability, and use ethtool with extending
the user-def option to configure Rx flow classification.
The new user-def 0xAAAABBBBCCCCDDDD: BBBB is the 2 byte pattern while
AAAA corresponds to its offset in the packet. Similarly DDDD is the 2
byte pattern with CCCC being the corresponding offset. The offset ranges
from 0x0 to 0x1F7 (up to 504 bytes into the packet). The offset starts
from the beginning of the packet.
This feature can be used to allow customers to set flow director rules
for protocols headers that are beyond standard ones supported by
ethtool (e.g. PFCP or GTP-U).
Like for matching GTP-U's TEID value 0x10203040:

The original intent here is to allow commands during reset to succeed
without error when the device is disabled, to ensure that cleanup
completes normally during NIC close, where firmware is not necessarily
expected to respond.
The problem with faking success during reset's PCI disablement is that
unrelated ULP commands will also see inadvertent success during reset
when failure would otherwise be appropriate. It is better to return
a different error result such that reset related code can detect
this unique condition and ignore as appropriate.
Note, the pci_disable_device() when firmware is fatally wounded in
bnxt_fw_reset_close() does not need to be addressed, as subsequent
commands are already expected to fail due to the BNXT_NO_FW_ACCESS()
check in bnxt_hwrm_do_send_msg().

In situations where FW has crashed, the bnxt_hwrm_do_send_msg() call
will have to wait until timeout for each firmware message. This
generally takes about half a second for each firmware message. If we
try to unload the driver n this state, the unload sequence will take
a long time to complete.
Improve this by checking the health register if it is available and
abort the wait for the firmware response if the register shows that
firmware is not healthy. The very first message HWRM_VER_GET is
excluded from this check because that message is used to poll for
firmware to come out of reset during error recovery.

In order to read the firmware health status, we first need to determine
the register location and then the register may need to be mapped.
There are 2 code paths to do this. The first one is done early as a
best effort attempt by the function bnxt_try_map_fw_health_reg(). The
second one is done later in the function bnxt_map_fw_health_regs()
after establishing communications with the firmware. We currently
only set fw_health->status_reliable if we can successfully set up the
health register in the first code path.
Improve the scheme by setting the fw_health->status_reliable flag if
either (or both) code paths can successfully set up the health
register. This flag is relied upon during run-time when we need to
check the health status. So this will make it work better.
During ifdown, if the health register is mapped, we need to invalidate
the health register mapping because a potential fw reset will reset
the mapping. Similarly, we need to do the same after firmware reset
during recovery. We'll remap it during ifup.

CONFIG_HAVE_NET_DSA is a legacy leftover from the times when drivers
should have selected CONFIG_NET_DSA manually.
Currently, all drivers has explicit 'depends on NET_DSA', so this is
no more needed.
2. CONFIG_HAVE_NET_DSA dependencies became CONFIG_NET_DSA's ones.
- dropped !S390 dependency which was introduced to be sure NET_DSA
can select CONFIG_PHYLIB. DSA migrated to Phylink almost 3 years
ago and the PHY library itself doesn't depend on !S390 since
commit 870a2b5e4f ("phylib: remove !S390 dependeny from Kconfig");
- INET dependency is kept to be sure we can select NET_SWITCHDEV;
- NETDEVICES dependency is kept to be sure we can select PHYLINK.
3. DSA drivers menu now depends on NET_DSA.
Instead on 'depends on NET_DSA' on every single driver, the entire
menu now depends on it. This eliminates a lot of duplicated lines
from Kconfig with no loss (when CONFIG_NET_DSA=m, drivers also can
be only m or n).
This also has a nice side effect that there's no more empty menu on
configurations without DSA.
4. Kbuild will now descend into 'drivers/net/dsa' only when
CONFIG_NET_DSA is y or m.
This is safe since no objects inside this folder can be built without
DSA core, as well as when CONFIG_NET_DSA=m, no objects can be
built-in.

Enable returning FDIR completion status by checking the
ctrl_vsi Rx queue descriptor value.
To enable returning FDIR completion status from ctrl_vsi Rx queue,
COMP_Queue and COMP_Report of FDIR filter programming descriptor
needs to be properly configured. After program request sent to ctrl_vsi
Tx queue, ctrl_vsi Rx queue interrupt will be triggered and
completion status will be returned.
Driver will first issue request in ice_vc_fdir_add_fltr(), then
pass FDIR context to the background task in interrupt service routine
ice_vc_fdir_irq_handler() and finally deal with them in
ice_flush_fdir_ctx(). ice_flush_fdir_ctx() will check the descriptor's
value, fdir context, and then send back virtual channel message to VF
by calling ice_vc_add_fdir_fltr_post(). An additional timer will be
setup in case of hardware interrupt timeout.
