vxge: Check if FCS stripping is disabled by the firmware.
- Added a function to check if FCS stripping is disabled by the firmware, if
it is not disabled fail driver load.
- By default FCS stripping is disabled by the firmware. With this assumption
driver decrements the indicated packet length by 4 bytes(FCS length).
- This patch ensures that FCS stripping is disabled during driver load time.
