[PATCH] IB/core: Add more speed parsing in ib_get_eth_speed()

[Selvin Xavier <selvin.xavier@xxxxxxxxxxxx>]

From: Kalesh AP <kalesh-anakkur.purayil@xxxxxxxxxxxx>

The function ib_get_eth_speed() does not take consideration
of 50G, 56G, 100G and 200G speeds. Added these speeds parsing.
We are not considering the lane width now. This can be enhanced
later.

Also, refactored the code to use switch case instead of if-else.
