In Windows DevX returns the value of the current link speed
in bps rate, the conversion to the Mbps rate expected by DPDK
is incorrect and fixed.

There is no previous commit with net/mlx5/windows as title prefix.
In general, there is "on Windows" at the end of the title.
This way we can have the same formatting when fixing the common code
for a Windows case.

"was" incorrect.

I think you should explain the confusion between Mbit/s and Mibit/s.
