Hi,
This cleans up some CSA related stuff and notably
tries to fix locking issues.
Now local->mtx is used along with sdata lock to
secure vif->csa_active modification. Addition of
local->mtx makes it possible to check
vif->csa_active on all interfaces safely.
The last patch (the revert) is more of a
suggestion.
I've decided to include the radar patch here as
well.
This patchset is required to support
multi-interface CSA in mac80211.
Changes since RFC:
* rebase on top of mac80211-next and adjust to
some IBSS/mesh changes
* fix typo in commit message of `move
csa_active seting in STA CSA`
* remove `track CSA globally`
* add `deny attempts at using chanctx during CSA`
(it takes a little bit of code from the removed
`track CSA globally` and `implement
multi-interface CSA`)
