Ruslan,

thanks for the patch. I applied it but what I get now is the MAC
address zeroed for all the interfaces:

ste0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=8<VLAN_MTU>
	ether 00:00:00:00:00:00
	media: Ethernet autoselect (100baseTX <full-duplex>)
	status: active
ste1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=8<VLAN_MTU>

Let me know if you need further testing or infos.
