Subject: [B.A.T.M.A.N.] [PATCH] batman-adv: Allow selecting BATMAN V if CFG80211 is not built
Date: Tue, 20 Sep 2016 15:59:17 +0200	[thread overview]
Message-ID: <20160920135917.24290-1-linus.luessing@c0d3.blue> (raw)

With the new stub for cfg80211_get_station(), we can now build the
BATMAN V protocol even with a kernel that was built without any
wireless support.
