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/ Signed-off-by: Ajit Khaparde <ajitk@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net>
