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
