Hi Michal
Does ETHA_EVENT_RENAMEDEV actually contain enough information to avoid
needing a rtnetlink lookup? If i understand the code correctly, all
you have is the new name. You don't know the old name?
Having said that, i don't see an easy way to get access to the old
name when handling the NETDEV_CHANGENAME.
