[PATCH] 8139too: send NETDEV_CHANGE manually when autoneg is disabled

[Veaceslav Falico <vfalico@redhat.com>]

When setting autoneg off (with any additional parameters, like
speed/duplex), 8139too doesn't do an interface reset, and thus doesn't
notify anyone that its speed/duplex might have changed (bonding and bridge
will not see the speed changes, per example).

Verify if we've force_media and send notification manually, so that the
listeners have a chance to see the changes. It's quite ugly, however I
don't see anything better.
