llc2: Remove the station send queue
We only ever put one skb on the send queue, and then immediately send it. Remove the queue and call dev_queue_xmit() directly. This leaves struct llc_station empty, so remove that as well. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
