</p><p>
This structure is placed in skb->cb for three uses:
(1) mac80211 TX control - mac80211 tells the driver what to do
(2) driver internal use (if applicable)
(3) TX status information - driver tells mac80211 what happened
</p><p>
The TX control's sta pointer is only valid during the ->tx call,
it may be NULL.
