It could be any number of daemons that query interface state such as an
SNMP server, ladvd, etc.
If you wanted help you could modify the patch so that it does something like
this:
if (/* test for IFF_UP */) {
BGE_UNLOCK(sc);
if_printf(ifp, "state queried on down interface by pid %d (%s)",
curthread->td_proc->p_pid, curthread->td_proc->p_comm);
return;
}
