I want to change individual (virtual) stations, so it seems easiest to
tell supplicant to set them as part of it's configuration logic.  I
have some fairly simple patches that appear to do some of this,
but it's all on top of my other patches.

For now, I'd rather spend effort getting my existing hostap patches upstream patch sets are becoming a total pain.  When I get that sorted I'll
post these mode-forcing patches.
