Yay! So I got hostapd working without the management interface,
that lets me remove it. Less code than I thought though.
It works like this but there are two minor TODO items,
injection needs to be able to
* specify QoS parameters
* circumvent PAE/802.1X checks
Oh and somebody needs to fix zd1211rw-mac80211. It abused the
MGMT interface constant that was explicitly mentioned to be
not for drivers... I've "fixed" it for now but readers of the
code may not be happy with it.
