Thanks. I missed that.

But there doesn't seem to be a vht_supported() from what I can tell.
ht_supported() seems to be based on 802.11n spec, but I don't have
access to 802.11ac spec.

Do you know what should be checked to verify vht support in this case?
Is it similar to 11n that a single spatial stream with mcs 0-7 (the
minimal rate subset I suppose) is required for non-AP STA in 11ac or
that the first stream mcs bitmask is set to either 0,1,2 (3 meaning
not supported)?

Pozdrawiam / Best regards,
