Bug description:
  Connect Hi1822 NIC with 10G switch but the performance is only 1-2Gb/s
  $ iperf -c
  Client connecting to, TCP port 5001
  TCP window size: 85.0 KByte (default)
  [  3] local port 56810 connected with port 5001
  [ ID] Interval       Transfer     Bandwidth
  [  3]  0.0-10.0 sec  1.53 GBytes  1.32 Gbits/sec

  [Test Case]
  iperf -c <server>

  Backporting all patches from mainline for drivers/net/ethernet/huawei solves 
this issue.

  [Regression Risk]
  Only modify codes in drivers/net/ethernet/huawei. Lowest risk to other 
devices and platform without it.
