It is an AMD amd64 machine, not running Xen.

I don't know whether it should support MSI-X or not, I am running a
custom kernel on it which did not contain wmimsi and acpiwmi but adding
them makes no difference. Is there anything else that should be added ?

Output of ifconfig -v is:

Also tried with all offloading options turned off, no change.

Running tcpdump on another machine shows it sending ARP requests.

Version 1.350 of if_wm.c works.
