Subject: [PATCH] bgmac: start/stop PHY on netdev open/stop

I've realized that I need to call ethtool command to get Ethernet
working after booting. Ex call: ethtool -s eth0 autoneg on
It was fixing Ethernet even if auto-negotiation was already on.

Adding calls to phy_start and phy_stop look like a real solution.
