[v3,00/22] net/ena: update ENA PMD to v2.3.0

  Hi,

this version updates the driver to version 2.3.0, which fixes multiple
bugs, contains part of the work on making the ENA PMD fully MP aware, and
also updates HAL to the latest version.

More detailed list of changes:
  * memcpy mapping to the dpdk-optimized version.
  * ena_com (HAL) update to the latest version.
  * Bug fixes for the large LLQ headers and devargs parsing.
  * Mbuf RSS hash presence indication.
  * Bug fix for the default ring size.
  * Various fixes for the SMP mode.

v3:
* Fix build of the PMD with the debug flags enabled.
* Fix typo in the commit log of the version upgrade patch.

v2:
* Fix nested declaration of the rte_memcpy on arm64 architecture.

Hi Michal,

There are some checkpatch and check-git-log.sh [1] warnings, can you please
check them?


You can see checkpatch warnings from patchwork:
https://patches.dpdk.org/project/dpdk/list/?series=16861
The ones with yellow marker in the warning column.

Additionally I am getting following checkpatch warning, that is not seen in CI:
### net/ena/base: add dev arg to the logging macros

This must be because of the script version difference, cc'e Thomas, David &
Aaron for it.

Hi Michal,

I want to confirm if this set is for this release or for v21.08.

Since it is sent late, after -rc1, getting the series for the -rc3 won't give
you any time to test it properly or fix any new found issues before release.

My suggestion is to wait for next release, but can you please confirm if you
want to get the risk and get the patch for this release or wait for v21.08?

Thanks,
ferruh

Hi Ferruh,

as this ENA release mainly introduces HAL upgrade and some bug fixes,
we would like to take a risk and get the patches for this release if
you're ok with that. Of course we can postpone some changes to the
next release if needed, but although there are multiple patches, most
of them are not the big ones (and there are no new features).

Thanks,
Michal

Hi Ferruh,

sure, I'll check them all and fix whatever is possible. The problem is
with some of the HAL patches, which are just touching some lines on
which the checkpatch returns a warning. Many of them aren't related to
those patches, so I don't think we should fix them as part of those
commits (like the one you listed below, the following patch just adds
ena_dev as an extra input argument). Please let me know what you think
about that.

Thanks,
Michal

Hi Michal,

For the new code I think expectation is clear that it should fully comply the
coding convention, but for the base code we are more flexible, since it is
shared I understand that the small fixes may cause more maintenance cost.

Please try to fix as much as possible, at least please fix the obviously wrong
ones and fix the ones like below with best effort.

Thanks,
ferruh
