Bug description:
[Impact]
Connect Hi1822 NIC with 10G switch but the performance is only 1-2Gb/s
$ iperf -c 10.228.68.133
------------------------------------------------------------
Client connecting to 10.228.68.133, TCP port 5001
TCP window size: 85.0 KByte (default)
------------------------------------------------------------
[ 3] local 10.228.68.116 port 56810 connected with 10.228.68.133 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 1.53 GBytes 1.32 Gbits/sec
[Test Case]
iperf -c <server>
[Fix]
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.
