As I said, addrlen will no longer be in record (because it would have no meaning since length ot the addr is always dev->addr_len) >Can userspace create a mc_list >entry with the wrong size via netlink?

Finally this bit can be removed. Currently, after the bonding driver is changed/fixed (32a806c194ea112cfab00f558482dd97bee5e44e net-next-2.6), that's not possible for an addr with different length than dev->addr_len to be present in list. Removing this check as in new mc_list there will be no addrlen in the record.
