Subject: [PATCH] mac80211: drop 4-addr VLAN frames earlier if not
connected
If there's no station on the 4-addr VLAN interface, then frames
cannot be transmitted. Drop such frames earlier, before setting
up all the information for them.
We should keep the old check though since that code might be used
for other internally-generated frames.
