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.
