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.
