Daemons which send LLDP advertisements (e.g. ladvd and lldpd) need to
send frames on trunk member ports in order that the individual port can
be identified to the switch; currently there is a blanket restriction
on sending via these ports, the following diff changes this to permit
AF_UNSPEC and pseudo_AF_HDRCMPLT as suggested by Sten Spans (ladvd
author).
Comments? OK?
