How about abstracting it further and not making the helper depend on
bridge code. If we put the helper into netcf, we could make that
a more generic '-net netcf,helper=/usr/bin/netcf-helper' target,
with netcf doing the correct thing for the system configuration,
whether that is tap+bridge, tap+route, macvtap or something else
coming up. The helper would essentially become a black box for
providing a tap-like file descriptor with external connectivity.
