[dpdk-dev] [PATCH v3] net/ixgbe: fix link status

[Lunyuan Cui]

After ports reset, tx laser register will be reset. The link
status for 82599eb got from link status register was not correct.
Set tx laser disable when port resets.

ixgbe_flap_tx_laser_multispeed_fiber() can cause link status
change from down to up. This treatment should work after
port starts.
