Subject: [PATCH v2 13/13] mac80211: implement multi-vif in-place reservations
Date: Fri, 21 Mar 2014 14:47:31 +0100 [thread overview]
Message-ID: <1395409651-26120-14-git-send-email-michal.kazior@tieto.com> (raw)
In-Reply-To: <1395409651-26120-1-git-send-email-michal.kazior@tieto.com>
Multi-vif in-place reservations happen when
it's impossible to allocate more chanctx as per
driver combinations.
Such reservations aren't finalized until last
reservation interface calls in to use the
reservation.
This introduces a special hook
ieee80211_vif_chanctx_reservation_complete(). This
is currently an empty stub and will be filled in
by AP/STA CSA code. This is required to implement
2-step CSA finalization.
This also gets rid of driver requirement to be
able to re-program channel of a chanctx.
