I have an application that issues SIOCGIFMEDIA to check interface media
status, and logs an error when that fails on a vboxnet interface.
This change is based on the same support added to FreeBSD's if_tap
interface in SVN r238183, which is in turn based on DragonFly BSD commit
70d9a675bf5441cc854a843ead702d08928c37f3. Sponsored by ADARA Networks.
Ideally status would report 'active' only when a VM is attached to the
host-only interface, but I don't see a straightforward way to do so with
the decoupling between VBoxNetFlt and VBoxNetAdp -- so consider this a
query for further information on this point as well. As it stands it
reports 'active' always.
