Hi Grygorii

I'm not sure this works by design, more by chance. And i think this is
the only MAC driver which does this. Can i suggest you test net-next
frequently, and review phylib patches, because i expect it will break
again unless you keep a close eye on changes. Developers simply don't
expect two phys connected to one MAC.

       Thanks
