wpa: pass IFM_IEEE80211_VHT5G if vht_enabled on the channel

[bz]

Summary

I believe this is needed in order to set media mode correctly to
IFM_IEEE80211_VHT5G if vht_enabled is set ont he channel.
Otherwise we'll end up setting 11NA.

Test Plan

At the moment this is still chicken-and-egg to be tested
but I don't want to lose the change.

LGTM

Adding wireless given @adrian is also working on VHT currently and will need this soon.

it's not entirely required because net80211 actually does the HT and VHT upgrade for us. I'll go check it first though to make sure it doesn't cause drama!

This is for the ifp media; I cannot see where the HT code would enable VHT media...

here's what i see in ifconfig:

.. is that "right" ? Or is one of the strings in media: supposed to be different?

Seems 656d0e8fa92ad72626808479d0935814425ee78d fixed what is reported back back on channel.

Break to ddb and show me vap->iv_des_mode (you can print the vap); I would assume it is 1 and not 13.

Reporting iwlwifi can as well but that doesn't mean it's doing.
mode is simply that the channel is VHT capable.

The interesting bit is when autoselect goes away and shows actual media.
This is without the patch as well btw.

aha! ok. I think NOW I get it. :-)
