Add software TSO support for FEC. This feature allows to improve outbound throughput performance. Tested on imx6dl sabresd board, running iperf tcp tests shows: - 16.2% improvement comparing with FEC SG patch - 82% improvement comparing with NO SG & TSO patch $ ethtool -K eth0 tso on $ iperf -c 10.192.242.167 -t 3 & [ 3] local 10.192.242.108 port 35388 connected with 10.192.242.167 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0- 3.0 sec 181 MBytes 506 Mbits/sec During the testing, CPU loading is 30%. Since imx6dl FEC Bandwidth is limited to SOC system bus bandwidth, the performance with SW TSO is a milestone.
