Hi,

I am running the 6.0 release on a supermicro 5015M-MF motherboard
with intel's 82573v dual gigE. by default only one of the two
ports are detected, although i was able to get both to work
following the advice here
http://www.freebsd.org/cgi/query-pr.cgi?pr=94281

the real puzzling thing is that em0 would send out a gratuitous arp
every 2 seconds with the IP address of 192.168.0.18 even though I
configured it to have a completely different IP address,
10.10.10.252. also, i was only able to see these arp messages on a
machine that is directly connected to em0. tcpdump on em0 doesnt
show any of the arp packets.

I searched my /etc and also the kernel source tree, and this
particular ip is nowhere to be found. Is the card doing this crazy
thing all by itself??

You may have an IPMI capable board for remote management and
monitoring. Turn it off from BIOS configuration if you can.
