Hi Deren,

just out of my curiosity, what are the possible values of cap->max_bw here?

Lorenzo

Hi Lore,

The definition of cap->max_bw is identical to
ieee80211_sta_rx_bandwidth. For now, the value would be 
IEEE80211_STA_RX_BW_160 if the chip supports bw160.


Regards,
Deren

ok, so why not something like:

dev->phy.cap.has_bw160 = cap->max_bw == IEEE80211_STA_RX_BW_160;

Hi Lore,

Sure, we should do the assignment preciesly. I will update next
version.
