STRUCT IEEE80211_TX_(9) The basic mac80211 driver inte STRUCT IEEE80211_TX_(9)NAME
struct_ieee80211_tx_info - skb transmit information
SYNOPSIS
struct ieee80211_tx_info {
u32 flags;
u8 band;
u8 hw_queue;
u16 ack_frame_id;
union {unnamed_union};
};
MEMBERS
flags
transmit info flags, defined above
band
the band to transmit on (use for checking for races)
hw_queue
HW queue to put the frame on, skb_get_queue_mapping gives the AC
ack_frame_id
internal frame ID for TX status, used internally
{unnamed_union}
anonymous
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

STRUCT IEEE80211_RX_(9) The basic mac80211 driver inte STRUCT IEEE80211_RX_(9)NAME
struct_ieee80211_rx_status - receive status
SYNOPSIS
struct ieee80211_rx_status {
u64 mactime;
enum ieee80211_band band;
int freq;
int signal;
int noise;
int antenna;
int rate_idx;
int flag;
};
MEMBERS
mactime
value in microseconds of the 64-bit Time Synchronization Function (TSF) timer when the first data symbol (MPDU) arrived at the
hardware.
band
the active band when this frame was received
freq
frequency the radio was tuned to when receiving this frame, in MHz
signal
signal strength when receiving this frame, either in dBm, in dB or unspecified depending on the hardware capabilities flags
IEEE80211_HW_SIGNAL_*
noise
noise when receiving this frame, in dBm.
antenna
antenna used
rate_idx
index of data rate into band's supported rates or MCS index if HT rates are use (RX_FLAG_HT)
flag
RX_FLAG_*
DESCRIPTION
The low-level driver should provide this information (the subset supported by hardware) to the 802.11 code with each received frame, in the
skb's control buffer (cb).
