Sorry for late handling. I wanted to solve Milan Obuch's issue first
before committing vr(4). But it seems that it's not easy to fix
Milan's issue. :-(

I'm sure I'll MFC the change to RELENG_7 but not sure it could be
done on RELENG_6 due to lack of spare time.

Link state change handling includes the following events which
could be happend during Tx/Rx operation or idle state against link
partner.
 o link up/down event.
 o link speed changes.
 o duplex changes.
 o flow-control changes(Not activated yet in vr(4)).
I guess overhauled vr(4) can handle all above events.
