.SH "MEMBERS"
.PP
band
.RS 4
band this channel belongs to\&.
.RE
.PP
center_freq
.RS 4
center frequency in MHz
.RE
.PP
hw_value
.RS 4
hardware\-specific value for the channel
.RE
.PP
flags
.RS 4
channel flags from
enum
ieee80211_channel_flags\&.
.RE
.PP
max_antenna_gain
.RS 4
maximum antenna gain in dBi
.RE
.PP
max_power
.RS 4
maximum transmission power (in dBm)
.RE
.PP
max_reg_power
.RS 4
maximum regulatory transmission power (in dBm)
.RE
.PP
beacon_found
.RS 4
helper to regulatory code to indicate when a beacon has been found on this channel\&. Use
\fBregulatory_hint_found_beacon\fR
to enable this, this is useful only on 5 GHz band\&.
.RE
.PP
orig_flags
.RS 4
channel flags at registration time, used by regulatory code to support devices with additional restrictions
.RE
.PP
orig_mag
.RS 4
internal use
.RE
.PP
orig_mpwr
.RS 4
internal use
.RE
.PP
dfs_state
.RS 4
current state of this channel\&. Only relevant if radar is required on this channel\&.
.RE
.PP
dfs_state_entered
.RS 4
timestamp (jiffies) when the dfs state was entered\&.
.RE
.PP
dfs_cac_ms
.RS 4
DFS CAC time in milliseconds, this is valid for DFS channels\&.
.RE
.SH "DESCRIPTION"
