bnx2x: Pause settings
Pause settings - 1G pause was not working due to missing write to the emac block (TX_MODE_FLOW_EN) - The flow control should use the negotiated result (after autoneg) so we should save both the requested autoneg and the result - The HW credits with flow control at 1G speed were not optimized and caused low throughput - It is recommended to turn off flow control if the MTU is bigger than 5000B due to internal buffers size Signed-off-by: Yaniv Rosner <yanivr@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
