* @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).
*
* @remain_on_channel: Starts an off-channel period on the given channel, must
* call back to ieee80211_ready_on_channel() when on that channel. Note
* that normal channel traffic is not stopped as this is intended for hw
* offload. Frames to transmit on the off-channel channel are transmitted
* normally except for the %IEEE80211_TX_CTL_TX_OFFCHAN flag. When the
* duration (which will always be non-zero) expires, the driver must call
* ieee80211_remain_on_channel_expired(). This callback may sleep.
* @cancel_remain_on_channel: Requests that an ongoing off-channel period is
* aborted before it expires. This callback may sleep.
