Can anyone tell me how to implement the .set_antenna interface function of mt7603

the
.set_antenna = mt76x2_set_antenna, //mt7603 not have
.get_antenna = mt76x2_get_antenna, //mt7603 not have
ieee80211 standard interface but is not have on mt7603 drive.

const struct ieee80211_ops mt76x2_ops =
{
.tx = mt76x02_tx,
.start = mt76x2_start,
.stop = mt76x2_stop,
.add_interface = mt76x02_add_interface,
.remove_interface = mt76x02_remove_interface,
.config = mt76x2_config,
.configure_filter = mt76x02_configure_filter,
.bss_info_changed = mt76x02_bss_info_changed,
.sta_state = mt76_sta_state,
.set_key = mt76x02_set_key,
.conf_tx = mt76x02_conf_tx,
.sw_scan_start = mt76x02_sw_scan,
.sw_scan_complete = mt76x02_sw_scan_complete,
.flush = mt76x2_flush,
.ampdu_action = mt76x02_ampdu_action,
.get_txpower = mt76_get_txpower,
.wake_tx_queue = mt76_wake_tx_queue,
.sta_rate_tbl_update = mt76x02_sta_rate_tbl_update,
.release_buffered_frames = mt76_release_buffered_frames,
.set_coverage_class = mt76x02_set_coverage_class,
.get_survey = mt76_get_survey,
.set_tim = mt76x2_set_tim,
.set_antenna = mt76x2_set_antenna, //mt7603 not have
.get_antenna = mt76x2_get_antenna, //mt7603 not have
.set_rts_threshold = mt76x02_set_rts_threshold, //mt7603 not have
}

in the mt7603 drive is
const struct ieee80211_ops mt7603_ops = {
.tx = mt7603_tx,
.start = mt7603_start,
.stop = mt7603_stop,
.add_interface = mt7603_add_interface,
.remove_interface = mt7603_remove_interface,
.config = mt7603_config,
.configure_filter = mt7603_configure_filter,
.bss_info_changed = mt7603_bss_info_changed,
.sta_state = mt76_sta_state,
.set_key = mt7603_set_key,
.conf_tx = mt7603_conf_tx,
.sw_scan_start = mt76_sw_scan,
.sw_scan_complete = mt76_sw_scan_complete,
.flush = mt7603_flush,
.ampdu_action = mt7603_ampdu_action,
.get_txpower = mt76_get_txpower,
.wake_tx_queue = mt76_wake_tx_queue,
.sta_rate_tbl_update = mt7603_sta_rate_tbl_update,
.release_buffered_frames = mt7603_release_buffered_frames,
.set_coverage_class = mt7603_set_coverage_class,
.set_tim = mt76_set_tim,
.get_survey = mt76_get_survey,
};

Start with the mt7603_ops and mt76x2_ops definitions shown in the issue, then trace the referenced mt76x2_set_antenna and mt76x2_get_antenna entry points. Determine whether the mt7603 hardware supports these mac80211 operations and what corresponding behavior is required; done means the requested interface is correctly supported or its limitation is clearly established.
