DESCRIPTION

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

The TX control's sta pointer is only valid during the ->tx call, it may be NULL.
