Hi folks,
I have a V440 which comes with two GigaSwift ethernet
interfaces built in.

First card is connected to network and working fine.
When I try to add the second card, it appears to have the
same Mac Adress !! These should be unique.

Any ideas what the problem is and how to resolve it.
Without a reboot if possible !!

Thanks a lot.

# grep network /etc/path_to_inst
"/pci at 1c,600000/network at 2" 0 "ce"
"/pci at 1f,700000/network at 1" 1 "ce"

# ifconfig ce1 plumb
# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
        inet netmask ff000000
ce0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet netmask ffffff00 broadcast
        ether 0:3:ba:56:42:8d
