hey all,
    i've got a question regarding ARP on FreeBSD 4.10.  I have two 
machines (archiver and homer).  each machine has two interfaces, one on 
our 100Base-T LAN and another on our seperate Gig-E LAN.  Each interface 
is given a different name, so the gig-e interface for homer is 
gate-homer (don't ask why we use gate-hostname wierd SGI thing...).  
Anyway when I perform a large NFS copy via the "gate" interfaces is get 
this error in my syslog:

arp: is on em0 but got reply from xx:xx:xx:xx:xx:ee on fxp0
(let's pretend that's a valid MAC address, the last two bits are the 
only interesting part anyway).

sure enough the MAC address that ends in :ee is the MAC addr. for the 
100Base-T connection on the NFS server, not the mounted gig-e 
interface.  wierd eh?  So what's happening, does anyone have an idea?
