Driver is not supporting hardware encryption and therefore fully
compatible with Extended Key ID.
On this particular patch now reading this I'm wondering if we shouldn't
just do that in mac80211 if there's no set_key callback? I suspect
that'd affect a few drivers that are otherwise more or less orphaned.
Good idea.
It's costing next to nothing to enable it for for drivers without a
set_key() callback, so I've just released v2 of the patch doing exactly
that. I kept all the information what has changed since the last RFC
series in the cover letter and the patches, so you can just ignore v1 of
the patch and directly move to v2.
