be2net: Changes to support flashing of the be2 network adapter
Changes to support flashing of the be2 network adapter using the
request_firmware() & ethtool infrastructure. The trigger to flash the device
will come from ethtool utility. The driver will invoke request_firmware()
to start the flash process. The file containing the flash image is expected
to be available in /lib/firmware/
