Bug Description
[Impact]
kernel oops
[Test Case]
Run netperf between two hosts. Doesn't 100% cause a crash, but works as a regression test.
[Fix]
d394d33bee224 net: hns3: add dma_rmb() for rx description
[Regression Risk]
Restricted to a driver specific to the hi1620 SoC. Since this adds a new read barrier, there is a potential performance regression risk.
