Bug Description
[Impact]
The hns driver we're shipping in hwe-z lacks a number of performance improvements and bug fixes that have since landed upstream prior to v4.12-rc4.
[Test Case]
Use iperf to confirm functionality, and no obvious loss of performance.
= Before =
Duplex:
$ iperf -c <targetIP> -P 8 -d -t 30
941 Mbits/sec
Simplex:
$ iperf -c <targetIP> -P 8 -t 30
942 Mbits/sec
= After =
Duplex:
$ iperf -c <targetIP> -P 8 -d -t 30
942 Mbits/sec
Simplex:
$ iperf -c <targetIP> -P 8 -t 30
942 Mbits/sec
[Regression Risk]
Changes are restricted to the hns driver, which is only used on HiSilicon SoCs. All changes are clean cherry-picks from upstream, so any regressions will have upstream support.
