All I can say is "me too". I am trying to netboot a poweredge R200, which
has two bge0 Broadcom BCM5721. Tried both NetBSD-current/amd64 and i386.
The NFS server is NetBSD-current/amd64 with nfe0.

Netbooting OK up to point where root partition needs nfs mounting. I can
use a root partition on a CD. Can mount the nfs root partition on /mnt.
chroot /mnt then hangs, or tar -xzvpf - from tar files on nfs mounted
partitions hangs. tcpdump shows 17 byte udp packets sent every now and
then from server to client. Nothing else is going on. (no response from
client back to server).

Cheers,
