SYNOPSIS
       struct ieee80211_channel {
         enum nl80211_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;
         unsigned int dfs_cac_ms;
       };

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.

       dfs_cac_ms
           DFS CAC time in milliseconds, this is valid for DFS channels.

DESCRIPTION
       This structure describes a single channel for use with cfg80211.
