Rafał Miłecki 57cad53f4e bcm4908: enable & setup packet steering 
Without packet steering NAT masquarade speed on BCM4908 /jumps/ between
two speeds:
1. 826 Mb/s (±3 Mb/s)
2. 909 Mb/s (±8 Mb/s)
and it never reaches ~940 Mb/s.

Proper packet steering can improve it. Below are testing results for
running iperf TCP traffic from LAN to WAN. They were used to pick up
golden values.
