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

struct_ieee80211_conf - configuration of the device SYNOPSIS
struct ieee80211_conf { u32 flags; int power_level; int dynamic_ps_timeout; int max_sleep_period; u16 listen_interval; u8 ps_dtim_period; u8 long_frame_max_tx_count; u8 short_frame_max_tx_count; struct ieee80211_channel * channel; enum nl80211_channel_type channel_type; enum ieee80211_smps_mode smps_mode; }; MEMBERS
flags configuration flags defined above power_level requested transmit power (in dBm) dynamic_ps_timeout The dynamic powersave timeout (in ms), see the powersave documentation below. This variable is valid only when the CONF_PS flag is set. max_sleep_period the maximum number of beacon intervals to sleep for before checking the beacon for a TIM bit (managed mode only); this value will be only achievable between DTIM frames, the hardware needs to check for the multicast traffic bit in DTIM beacons. This variable is valid only when the CONF_PS flag is set. listen_interval listen interval in units of beacon interval ps_dtim_period The DTIM period of the AP we're connected to, for use in power saving. Power saving will not be enabled until a beacon has been received and the DTIM period is known. long_frame_max_tx_count Maximum number of transmissions for a "long" frame (a frame not RTS protected), called "dot11LongRetryLimit" in 802.11, but actually means the number of transmissions not the number of retries short_frame_max_tx_count Maximum number of transmissions for a "short" frame, called "dot11ShortRetryLimit" in 802.11, but actually means the number of transmissions not the number of retries channel the channel to tune to channel_type the channel (HT) type smps_mode spatial multiplexing powersave mode; note that IEEE80211_SMPS_STATIC is used when the device is not configured for an HT channel DESCRIPTION
This struct indicates how the driver shall configure the hardware. AUTHOR
