- 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.
