Also, here are a few more bits of information.

strace output from /sbin/ifconfig ecdbgm0 up:
(Lots of other output deleted)
socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 4
ioctl(4, SIOCGIFFLAGS, {ifr_name="ecdbgm0",
      ifr_flags=IFF_BROADCAST|IFF_MULTICAST}) = 0
ioctl(4, SIOCSIFFLAGS, 0x7fff09cf1eb0)  = -1 EINVAL (Invalid argument)



Thanks,
