Title:
Fix several bugs in RDMA/hns driver
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Bionic:
Fix Committed
Bug description:
[Impact]
Several issues and features in the RDMA/hns driver for HiSilicon network
adapters have recently landed upstream. This includes fixes for crashes and
endianness issues, among others.

[Regression Risk]
TLDR; this driver isn't usable today, so changes to it carry negligible
regression risk.
These patches are localized to the hns/RDMA driver. This driver is for
hardware in the hip07/hip08 SoCs, which Ubuntu supports in the D05 and
D06 servers respectively. D05 firmware has intentionally disabled this
feature by not exposing the ACPI ID for it. The driver therefore
doesn't find the device on that platform, so there is no regression
risk.
D06 *does* enable this device in firmware. However, the current bionic
kernel crashes when loading the base ethernet driver (hns3 - LP:
#1768670) on this platform, so this feature is also currently unusable
there.
