Bug description:
  [Impact]
  The throughput measured by iperf3 is around 70% of 1Gbps (Intel I219-LM
  [8086:15b7])
  I219 is a rather cheap NIC and it impacts its throughput if TSO(TCP
  segmentation offload) is enabled.                              
                          
  [Fix]                   
  Disable TSO on NIC and move this task back to CPU fixes this issue.
  The impact of CPU loading is little to none.
  On target machine with Xeon(R) CPU E3-1505L v6 @ 2.20GHz(4c8t), the CPU
  usage of iperf3 increases from 1% to 4%

  [ 4] 0.00-10.00 sec 1.09 GBytes 934 Mbits/sec receiver

  [Regression Potential]
  Low, disable TSO on Ethernet chip will move the TCP segmentation task
  to CPU. This increase CPU loading a little bit, and should not introduce
  any regression. 

  =============================

  Testing with iperf3 send speed is only 750mbps while receive speed is
  normal - 940mbps.
