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.
