!283 [OLK-5.10] Add debug print of 64G link speed

Merge Pull Request from: @xiaosuli3109 
 
Fibre Channel has been the standard connection type for storage area networks (SAN) in enterprise storage. Despite its name, Fibre Channel signaling can run on both twisted pair copper wire and fiber-optic cables.

The FibreChannel Gen7 adapter supports 64G link speeds. Add debug print support to the driver.
