proxy arp breaks qfe interface

[hi, i sent this through sendbug, but i didn't get a confirmation, so
i'm sending again. many apologies if it's a dup]

When I add a proxy arp to an interface on a Sun QuadFastEthernet card, it fails and seems to break the interface.

This machine is a Sun Ultra 5, with a QFE card in it. The relevant output of ifconfig:

hme0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500

hme1 is our internet-facing interface, and is connected to a 10bT hub.

When I add the proxy arp:

[root@egret etc]# arp -s 217.205.100.221 08:00:20:cb:4a:58 permanent pub
arp: writing to routing socket: No such process

At this point, the interface stops working (although all the others appear to be ok). The arp entry hasn't been added:

[root@egret root]# arp -na | grep 221

shows nothing.

Pinging from that interface shows nothing. If I then:

[root@egret root]# ifconfig hme1 down
[root@egret root]# ifconfig hme1 up
[root@egret root]# ping www.google.com

PING www.google.com (216.239.51.101): 56 data bytes

ping: sendto: Host is down
ping: wrote www.google.com 64 chars, ret=-1
ping: sendto: Host is down
ping: wrote www.google.com 64 chars, ret=-1

etc.

I had to reboot to get the interface working again.

dmesg follows.
