>Environment:
System : 4.10-RELEASE FreeBSD 4.10-RELEASE #2
Architecture: i386

>Description:
I have bridge set up on with 2 lan cards:

* interface dc0: has a statice IP 172.16.0.5 and MAC address 00:80:ad:74:c5:6d
* interface dc1:  has no IP (just up) and MAC address 00:80:ad:76:ce:d7
* dc0 and dc1 make bridge0

A second machine is connected to dc0 (using cross cable) directly or (Using staight cable) via switch and everything
works fine. 

But the log of that second machine get the following entries:
arp: 172.16.0.5 moved from 00:80:ad:74:c5:6d to 00:80:ad:76:ce:d7 on ne3
arp: 172.16.0.5 moved from 00:80:ad:76:ce:d7 to 00:80:ad:74:c5:6d on ne3
arp: 172.16.0.5 moved from 00:80:ad:74:c5:6d to 00:80:ad:76:ce:d7 on ne3
>How-To-Repeat:
Set up the same configuration: bridge with 2 interface, only 1 having an IP.
