mac80211: move TX info into skb->cb
This patch converts mac80211 and all drivers to have transmit
information and status in skb->cb rather than allocating extra
memory for it and copying all the data around. To make it fit,
a union is used where only data that is necessary for all steps
is kept outside of the union.
A number of fixes were done by Ivo, as well as the rt2x00 part
of this patch.
