Well, I see a few things here:

1) does it even make sense to split it out per AC? wouldn't it be weird
if you supported this only for VO and BK, and not the others, or
something like that?

2) Wouldn't it make more sense to define this in nl80211 and just pass
the bitmap through to userspace? That would save quite a bit of netlink
mangling complexity.

3) I think the naming is confusing - "WIPHY_BTCOEX_SUPPORTS_BE_PREF" or
so might be more appropriate?

I was more thinking of the capability advertisement, but yeah, both
ways seems reasonable.
