Subject: [PATCH] wl1251: fix null data for IBSS
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Fix the WARN below by not calling ieee80211_nullfunc_get() in IBSS mode,
but setting up empty template the same way wl12xx driver does.

WARNING: CPU: 0 PID: 914 at net/mac80211/tx.c:2750 ieee80211_nullfunc_get+0xc0/0xd0 [mac80211]()

[<bf099e14>] (ieee80211_bss_info_change_notify [mac80211])
...

Also perform join command regardless of bss_type as that seems to be
required for proper operation.
