bnx2x: 8073 PHY changes
8073 PHY changes The initial support we had for this PHY needs some serious changing. The major change is that this PHY should be initialized only when the first function is loaded and not for each function. The official SPI-ROM of this PHY was released and it requires some changes in the initialization code as well Signed-off-by: Yaniv Rosner <yanivr@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.
