Andrew reported a bonding issue that if we put an active-back bond on top
of a 802.3ad bond interface. When the 802.3ad bond's speed/duplex changed
dynamically. The upper bonding interface's speed/duplex can't be changed at
the same time, which will show incorrect speed.
Fix it by updating the port speed when calling ethtool.
