Subject: [PATCH v4 0/5] cfg80211/mac80211: implement multi-vif csa
Date: Wed, 9 Apr 2014 15:45:32 +0200 [thread overview]
Message-ID: <1397051137-26201-1-git-send-email-michal.kazior@tieto.com> (raw)
In-Reply-To: <1396267459-9976-1-git-send-email-michal.kazior@tieto.com>
Hi,
This is another part of my recent (originally)
RFC. This is just the channel switching part.
This is based on my patchset implementing
multi-vif chanctx reservations.
This effectively enables multi-vif CSA for
STA/AP/IBSS/mesh (except the fact that channel
switching itself is still hard-disabled in
cfg80211 -- maybe it's about time to re-enable?).
v2:
* add radar_detect fix patch (wasn't present in
the big RFC)
v3:
* remove radar_detect fix patch (it was
cherry-picked)
* squash removal of ieee80211_vif_change_channel() [Johannes]
* cleanups [Johannes]
* add resilience for calling ieee80211_csa_finish() and
ieee80211_chswitch_done() more than once (the
problem was originally discussed in `ath10k: dont call csa_finish
more than once`)
v4:
* fix compilation issue between 2/5 and 3/5
(I had squashed vif_change_channel removal too early)
Michal Kazior (5):
mac80211: make check_combinations() aware of chanctx reservation
mac80211: use chanctx reservation for AP CSA
mac80211: use chanctx reservation for STA CSA
mac80211: ignore cqm during csa
cfg80211: remove channel_switch combination check
