a box with de and xl interfaces plus BRIDGE and DUMMYNET compiled in,
doing a "sysctl -a" will panic the box. (currproc == sysctl)
i have both bridging and ipfw enabled on the bridged packets,
my de0 card has no ip and my xl0 card does.
if you aren't easily able to reproduce it, i'll try harder, i've
just been quite busy.
This is on -current as of a few days ago, and is still a problem on
-current today 5/2/99
Also, could someone consider this patch to the rc system to enable
bridging in network_pass1() ?
