After fixing mac80211 to allow larger A-MSDUs in some cases, there have been
reports of performance regressions and packet loss with some clients.
It appears that the issue occurs when the hardware is transmitting A-MSDUs
bigger than 8k. Limit the local VHT MPDU size capability to 7991, matching
the value used for MT7915 as well.

Two minor conflicts:
1) net/ipv4/route.c, adding a new local variable while
moving another local variable and removing it's
initial assignment.
2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes.
One pretty prints the port mode differently, whilst another
changes the driver to try and obtain the port mode from
the port node rather than the switch node.

====================
wireless-drivers-next patches for v5.10
First set of patches for v5.10. Most noteworthy here is ath11k getting
initial support for QCA6390 and IPQ6018 devices. But most of the
patches are cleanup: W=1 warning fixes, fallthrough keywords, DMA API
changes and tasklet API changes.
Major changes:
ath10k
* support SDIO firmware codedumps
* support station specific TID configurations
ath11k
* add support for IPQ6018
* add support for QCA6390 PCI devices
ath9k
* add support for NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 to improve PTK0
rekeying

* add support for TX ack

Using dev_kfree_skb for tx skbs breaks AQL. This worked until now only
by accident, because a mac80211 issue breaks AQL on drivers with firmware

The implementation of embedding WTBL update inside the STA_REC update is buggy
on the MT7615 v2 firmware. This leads to connection issues after a station has
connected and disconnected again.
Switch to the v1 MCU API ops, since they have received much more testing and
should be more stable.
On MT7622 and later, the v2 API is more actively used, so we should keep using
it as well.

Smatch complains that "wcidx" value comes from the network and thus
cannot be trusted. In this case, it actually seems to come from the
firmware. If your wireless firmware is malicious then probably no
amount of carefulness can protect you.
On the other hand, these days we still try to check the firmware as much
as possible. Verifying that the index is within bounds will silence a
static checker warning. And it's harmless and a good exercise in kernel
hardening. So I suggest that we do add a bounds check.
