Looks good. I have some changes to allow devices with multiple MAC addresses
(never finished). This device could use that.
How would the driver do that? I was thinking about using dev_add_mc,
but wasn't sure if that would work with all drivers for non-multicast
addresses.
This is actually a real issue for virtualization, and many
if not all current generation ethernet chips support
programming several unicast ethernet addresses in the MAC.
Networking switches in domain0 on virtualization hosts use
this feature to support seperate MACs per guest node,
and if the chip doesn't support this the chip is put into
promiscuous mode.
We don't have any clean interfaces by which to do this MAC
programming, and we do need something for it soon.
Stephen's suggestion sounds reasonable and easily implementable,
I'll see if I can come up with a patch.
