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.
