bnx2x: Supporting PHY FW upgrade
There are 3 operations that the driver needs to support to allow applications to access the PHY FW (on top of the MDC/MDIO access). Since those are essentially nvram access commands, adding them to the ethtool -E interface. Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
