From a7a6bdd0670feb8bfc26d41cda32b6064dbca50e Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Sun, 9 Nov 2014 18:50:19 +0200 Subject: mac80211: introduce TDLS channel switch ops Implement the cfg80211 TDLS channel switch ops and introduce new mac80211 ones for low-level drivers. Verify low-level driver support for the new ops when using the relevant wiphy feature bit. Also verify the peer supports channel switching before passing the command down. Add a new STA flag to track the off-channel state with the TDLS peer and make sure to cancel the channel-switch if the peer STA is unexpectedly removed.
