}; band this channel belongs to.
center frequency in MHz
hardware-specific value for the channel
channel flags from enum ieee80211_channel_flags.
maximum antenna gain in dBi
maximum transmission power (in dBm)
maximum regulatory transmission power (in dBm)
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.
channel flags at registration time, used by regulatory code to support devices with additional restrictions
internal use
internal use
current state of this channel. Only relevant if radar is required on this channel.
timestamp (jiffies) when the dfs state was entered.
DFS CAC time in milliseconds, this is valid for DFS channels.
