[net 04/10] ixgbe: Fix link issues caused by a reset while interface is down

From: Emil Tantilov <redacted>

Interface fails to obtain link on 82599 SFP in the following scenario:

1. Set advertised speed to GB:
ethtool -s eth0 advertise 0x20

2. Bring interface down
ip link set eth0 down

3. Issue any command that leads to a reset:
ethtool -t eth0

4. Bring link back up:
ip link set eth0 up

Following patch makes sure that the driver flaps the Tx laser every time
ixgbe_start_hw() is called, and not only when the speed is set.
