Subject: wl12xx: remove warning message during IBSS Tx
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=48309fd477ef867babb6819f67fe082c133a5fa9;p=linux-beck.git

wl12xx: remove warning message during IBSS Tx

mac80211 sets the carrier on an IBSS interface even when no network is
joined. Ignore garbage frames transmitted on a disconnected IBSS
interface without printing warnings.
