From: Luca Coelho <[email protected]>
Hi,
This is the first patchset with fixes for v5.12.
The changes are:
* A few locking fixes;
* Fix a workaround for devices of the 22000 family;
* Fix the position of a bit in the regulatory capabilities;
* Add support to some devices that were missing.
As usual, I'm pushing this to a pending branch, for kbuild bot. And
since these are fixes for the rc series, please take them directly to
wireless-drivers.git, as we agreed. I'll assign them to you.
Cheers,
Luca.

We have a new type of device that has a different MAC ID, but is
otherwise identical to So devices. Add rules to match this new ID
accordingly.

2.31.0
From: Johannes Berg <[email protected]>
Unfortunately, since beacon protection isn't fully available
yet, we didn't notice that there are problems with it and
that the replay detection isn't working correctly. We were
relying only on mac80211, since iwl_mvm_rx_crypto() exits
when !ieee80211_has_protected(), which is of course true for
protected (but not encrypted) management frames.
Fix this to properly detect protected (but not encrypted)
management frames and handle them - we continue to only care
about beacons since for others everything can and will be
checked in mac80211.

Oops, I misinstalled my hooks and ended up sending all the patches with
Change-Id tags. Sorry for that and thanks Johannes for noticing.
I'll mark this series as superseded and send v2.
