When setup monitor mode in DFS channel, mt76 send CH_SWITCH_DFS to
fw for channel config. This would cause rx performance bad while
monitoring frames. Settings CH_SWITCH_NORMAL in monitor mode would
get the same performance as normal channels.

IEEE80211_CONF_CHANGE_MONITOR would be set every time even when vif runs as
sta mode.
If vif runs as sta mode, the beacon filter would be falsely enabled
earlier than the associated state.
That is not the behavior the firmware expects and also breaks the original
logic of sta mode. Thus, we only limit the operation to set the beacon
filter only for monitor mode when IEEE80211_CONF_CHANGE_MONITOR is set.

mt7921s driver may receive frames with fragment buffers. If there is a
CTS packet received in monitor mode, the payload is 10 bytes only and
need 6 bytes header padding after RXD buffer. However, only RXD in the
first linear buffer, if we pull buffer size RXD-size+6 bytes with
skb_pull(), that would trigger "BUG_ON(skb->len < skb->data_len)" in
__skb_pull().
To avoid the nonlinear buffer issue, enlarge the RXD size from 128 to
256 to make sure all MCU operation in linear buffer.
