struct ieee80211_tx_info — skb transmit information
struct ieee80211_tx_info {
u32 flags;
u8 band;
u8 antenna_sel_tx;
u8 pad[2];
union {unnamed_union};
}; transmit info flags, defined above
the band to transmit on (use for checking for races)
antenna to use, 0 for automatic diversity
padding, ignore
anonymous
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.
