From: Kalesh AP <kalesh-anakkur.purayil@xxxxxxxxxxxx>
When the Ethernet driver does not provide the number of lanes
in the __ethtool_get_link_ksettings() response, the function
ib_get_width_and_speed() does not take consideration of 50G,
100G and 200G speeds while calculating the IB width and speed.
Update the width and speed for the above netdev speeds.

v1 - v2:
- Rebased the patch based on the latest changes in ib_get_width_and_speed
- removed the switch case and use the existing else if check
