IEEE80211_GENERIC_FR(9) The basic mac80211 driver inte IEEE80211_GENERIC_FR(9)NAME
ieee80211_generic_frame_duration - Calculate the duration field for a frame
SYNOPSIS
__le16 ieee80211_generic_frame_duration(struct ieee80211_hw * hw, struct ieee80211_vif * vif, enum ieee80211_band band, size_t frame_len,
struct ieee80211_rate * rate);
ARGUMENTS
hw
pointer obtained from ieee80211_alloc_hw.
vif
struct ieee80211_vif pointer from the add_interface callback.
band
the band to calculate the frame duration on
frame_len
the length of the frame.
rate
the rate at which the frame is going to be transmitted.
DESCRIPTION
Calculate the duration field of some generic frame, given its length and transmission rate (in 100kbps).
RETURN
The duration.

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).
