Currently I'm thinking the way. What I have on mind:
I would like to add a list into struct net_device to contain all mac addresses
of the device. I would also like to use similar interface to handle them as
currently is for uc_list and mc_list. However I do not like that these lists are
not using standard list_head but they are propriate lists only for this purpose.
I'm thinking about converting them to use list_head first. Or maybe ignore them
and do the new list for macs in parallel?

Using list_heads in the address lists would require some pretty large
amount of work since you'd need to convert all the drivers. I'm all
in favour of doing this, but I wouldn't make the fix depend on that
work.
