From: Ilan Peer <[email protected]>
It is possible that the station is connected to an AP
with bandwidth of 80+80MHz or 160MHz. In such cases
there is no need to perform an upgrade as the maximal
supported bandwidth is 80MHz.
In addition, when upgrading and setting center_freq1
and bandwidth to 80MHz also set center_freq2 to 0.
