Public bug reported:
[Impact]
A number of changes for the RDMA/hns driver landed upstream post-5.0, including
a number of bug fixes, corrections for consistency w/ the hip08 SoC spec, as
well as a couple new features and cleanup. I recommend we sync up the changes
for disco so that we have an established base for future changes.
[Test Case]
Regression tested w/ perftest:
= server =
sudo ib_send_bw -d hns_2 -i 1 -a -F --report_gbits
= client =
sudo ib_send_bw -d hns_2 -i 1 -a -F --report_gbits <serverip>
