IEEE80211_CHA(9) Device registration STRUCT IEEE80211_CHA(9) NAME
struct_ieee80211_channel - channel definition SYNOPSIS
struct ieee80211_channel { enum ieee80211_band band; u16 center_freq; u16 hw_value; u32 flags; int max_antenna_gain; int max_power; int max_reg_power; bool beacon_found; u32 orig_flags; int orig_mag; int orig_mpwr; enum nl80211_dfs_state dfs_state; unsigned long dfs_state_entered; }; MEMBERS
band band this channel belongs to. center_freq center frequency in MHz hw_value hardware-specific value for the channel flags channel flags from enum ieee80211_channel_flags. max_antenna_gain maximum antenna gain in dBi max_power maximum transmission power (in dBm) max_reg_power maximum regulatory transmission power (in dBm) beacon_found helper to regulatory code to indicate when a beacon has been found on this channel. Use regulatory_hint_found_beacon to enable this, this is useful only on 5 GHz band. orig_flags channel flags at registration time, used by regulatory code to support devices with additional restrictions orig_mag internal use orig_mpwr internal use dfs_state current state of this channel. Only relevant if radar is required on this channel. dfs_state_entered timestamp (jiffies) when the dfs state was entered. DESCRIPTION
This structure describes a single channel for use with cfg80211. AUTHOR

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). AUTHOR
