From: Johannes Berg <johannes.berg@xxxxxxxxx>
We need to differentiate these frames since the ones we
currently put on the skb_queue_tdls_chsw have already
been converted to ethernet format, but now that we've
got a single place to enqueue to the sdata->skb_queue
this isn't hard. Just differentiate based on protocol
and adjust the code to queue the SKBs appropriately.
