> Fix 82599 link issues during driver load and unload test using multi-speed
> 10G & 1G fiber modules. When connected back to back sometime 82599 multispeed
> fiber modules would link at 1G speed instead of 10G highest speed, due to a
> race condition in autotry process involving Tx laser flapping. Move autotry
> autoneg-37 tx laser flapping process from multispeed module init setup
> to driver unload. This will alert the link partner to restart its
> autotry process when it tries to establish the link with the link partner
