My colleague and I have been trying to no avail to get the tests in the
rdma-core repository to pass. We have tried running the tests on variety
of different hardware at this point, but we keep running into numerous
and/or non-trivial failures, none of which have anything to do with the
MANA provider changes covered by the SRU (I would say with a very high
degree of confidence). I can't find anyone who has actually run these
tests, let alone successfully, so I don't know if they all work, even
when run against appropriately configured hardware.

I added the tests in the rdma-core repository to the SRU test plan
because the changes that I introduced touched files outside of the
providers/mana directory. Upon reconsideration, I realized that I can
limit the SRU changes to just the providers/mana directory and the file
kernel-headers/rdma/mana-abi.h without adversely affecting the MANA
provider functionality. I have prepared new Noble and Oracular package
versions that reflect this revised scope (see versions
50.0-2ubuntu0.2~ppa2 and 52.0-2ubuntu2.2~ppa1 in
https://launchpad.net/~danpdraper/+archive/ubuntu/rdma-core-
mana/+packages).

I would like to revise the SRU to target these new package versions
(after they are sponsored/uploaded to noble-devel and oracular-devel)
and revise the scope of the test plan to exclude the tests in the rdma-
core repository (none of which exercise the MANA provider). The rping
test described in the test plan exercises the MANA provider's
integration with the kernel and, by extension, the underlying hardware.
My contacts at Microsoft and I believe that the test is a sufficient
means of verifying that the changes are serving their intended purpose
(i.e., enabling RDMA through Microsoft Azure Network Adapters).

Note that the new package versions referenced above also include a patch
corresponding to https://github.com/linux-rdma/rdma-
core/commit/683218145c834eef0763e9624bb28e4960f768d5 , which was not
included in the package versions initially uploaded to noble-proposed
and oracular-proposed under this SRU.

I will update the bug description to reflect the revised test plan
scope. I will also remove the comments regarding the
ibv_cmd_reg_dmabuf_mr function from the "Other Info" section.
