Comment 15 for bug 1770003

Here is the set of patches I needed to backport/cherry-pick to get a kernel that would build.

11aea16ab3f5 scsi: qla2xxx: Add ability to send PRLO

I have this kernel built in a PPA: ppa:ubuntu-power-triage/lp1770003. This kernel needs to be tested on the platform (bug does not say if this was found in P8 or P9) where the issue was reported, and will also need to be tested on Cavium (ARM64) to make sure there are no regressions.
