IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160MHZ =vht160 only
IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160_80PLUS80MHZ = vht160 and 80+80
support
+ if ((ar->vht_cap_info & IEEE80211_VHT_CAP_SHORT_GI_160) &&
+ !(ar->vht_cap_info &
IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160_80PLUS80MHZ))
+ vht_cap.cap |= IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160MHZ;
+
so if the firmware itself doesnt contain the correct vht flags but just
short_gi_160 flag. i assume it supports vht160 and set the vht160 only
flag.
newer firmwares on codeaurora contain the correct flags. so this code
here gets avoided. unfortunatly the newer i found is also not stable and
crashes often.
you can also enable 80+80 support with the current firmware.but all
station ht and vht flags seem to be empty then in vht160 mode too. so it
might be a firmware issue still with 80+80 or mac80211.
i did not debug that much. but vht160 works. i also tested it now with a
88w6964 marvell client in vht160 which worked too
