From: Sven Eckelmann <sven@xxxxxxxxxxxxx>
commit 3f3f87325dcb3c201076c81490f4da91ad4c09fc upstream.
A wifi interface should never be handled like an ethernet devices. The
parser of the cfg80211 output must therefore skip the ethtool code when
cfg80211_get_station returned an error.
Fixes: f44a3ae9a281 ("batman-adv: refactor wifi interface detection")
