59ca9572de iwlwifi: mvm: use CHECKSUM_COMPLETE
On newer hardware, we have the full checksum, so use it to report
CHECKSUM_COMPLETE and avoid the protocol specific hardware parsing.

Note that the hardware already parses/removes the SNAP header, so
we actually literally get what we need to report to the stack, as
we're expected to checksum everything after the L2 header (which
is translated/added by mac80211).

cfa5d0ca0f iwlwifi: mvm: remove redundant support_umac_log field
Currently we have the same info in two variables,
If umac_error_event_table is 0, we know that UMAC log is not supported,
so we don't need the support_umac_log field.

2b3eb12234 iwlwifi: mvm: process ba-notifications also when sta rcu is invalid
The the driver prevents new Tx from being sent during the remove-station
flow is by invalidating the fw_id_to_mac_id rcu of that station.

However, if there was any Tx still in-flight (tx-cmd was sent but the
ba-notif wasn't received yet) the ba-response to those frames is simply
ignored without actually reclaiming anything. This later causes the
driver to think that that some of the station's queues aren't empty when
in practice they are which causes errors in the station remove flow.

Fix this by performing the tx-reclaim also if the rcu is invalid. any DB
that can't be updated due to this is not very important at this stage
since the station is about to be removed soon anyways.

A FTM responder may do PASN authentication with unassociated stations
to allow secure ranging. In this case, the driver will add an internal
station and install the TK so the FW will accept protected FTM
request frames from this station and will send a protected FTM
response frame.

In addition, the driver needs to configure the HLTK to the FW so
the FW can derive the secure LTF bits. This is left for a later
patch since it is not yet supported by the FW.

According to [1], platform firmware may not properly power manage the

D3 can workaround the issue.

So let's power cycle the device by putting the device to D3 at shutdown
to prevent the issue from happening.

d0151c2bad brcmfmac: Fix warning when hitting FW crash with flow control feature
Brcmfmac got warning message when hitting FW crash in TX throughput test
with fcmode=2. It's caused by FMAC flushed TXQ in brcmf_sdio_bus_stop
but without doing hanger slot cleanup. Therefore, we move
brcmf_remove_interface before brcmf_bus_stop to make sure the hanger
slot is clean when flushing TXQ.

6208689fb3 Merge branch 'introduce BPF_F_PRESERVE_ELEMS'
Song Liu says:

====================
This set introduces BPF_F_PRESERVE_ELEMS to perf event array for better
sharing of perf event. By default, perf event array removes the perf event
when the map fd used to add the event is closed. With BPF_F_PRESERVE_ELEMS
set, however, the perf event will stay in the array until it is removed, or
the map is closed.
---
Changes v3 => v5:
1. Clean up in selftest. (Alexei)

Changes v2 => v3:
1. Move perf_event_fd_array_map_free() to avoid unnecessary forward
   declaration. (Daniel)

Changes v1 => v2:
1. Rename the flag as BPF_F_PRESERVE_ELEMS. (Alexei, Daniel)
2. Simplify the code and selftest. (Daniel, Alexei)

792caccc45 bpf: Introduce BPF_F_PRESERVE_ELEMS for perf event array
Currently, perf event in perf event array is removed from the array when
the map fd used to add the event is closed. This behavior makes it
difficult to the share perf events with perf event array.

Introduce perf event map that keeps the perf event open with a new flag
BPF_F_PRESERVE_ELEMS. With this flag set, perf events in the array are not
removed when the original map fd is closed. Instead, the perf event will
stay in the map until 1) it is explicitly removed from the array; or 2)
the array is freed.

When removing a flow from the slow path fdb, a flow attr struct is
allocated for the rule removal process. If the allocation fails the
code prints a warning message but continues with the removal flow
which include dereferencing a pointer which could be null.
Fix this by exiting the function in case the attr allocation failed.

0172391967 net/mlx5: DR, Add support for rule creation with flow source hint
Skip the rule according to flow arrival source, in case of RX and the
source is local port skip and in case of TX and the source is uplink
skip, we get this info according to the flow source hint we get from
upper layers when creating the rule.
This is needed because for example in case of FDB table which has a TX
and RX tables and we are inserting a rule with an encap action which
is only a TX action, in this case rule will fail on RX, so we can rely
on the flow source hint and skip RX in such case.
Until now we relied on metadata regc_0 that upper layer mapped the
port in the regc_0, but the problem is that upper layer did not always
use regc_0 for port mapping, so now we added support to flow source
hint which upper layers will pass to SW steering when creating a rule.
