Description

Hi,

yesterday, when experimenting with udpxy, I noticed that multicast
does not work on re(4) unless I explicitly set the interface to
promiscuous mode. I tried the exact same setup on an xl0 interface and
it worked out of the box.

After comparing the re(4) sources with FreeBSD, I noticed that in
their re driver writes some data (some hash tables related to
multicast) in a different order. After implementing similar changes in
DragonFly, multicast seems to work (please see attached patch).

Regard,
Mitja Horvat
