[dpdk-dev] [PATCH 05/10] bus/dpaa: make vdqcr configurable

[Hemant Agrawal]

From: Nipun Gupta <nipun.gupta@nxp.com>

This patch add support for configurable vdqcr exact flag.
This boost the performance, however this can give
side effects for some extra packet fetch. Which has been
taken care in the patch as well.

[dpdk-dev] [PATCH 08/10] net/dpaa2: fix the prefetch Rx to honor nb pkts

[Hemant Agrawal]

This patch fix the prefetch rx routine to
set the next prefetch request to the size of nb_pkts.
This will assume that next request will ideally will be
of same size.

[dpdk-dev] [PATCH v2 05/16] net/dpaa2: fix the prefetch Rx to honor nb pkts

[Hemant Agrawal]

This patch fix the prefetch rx routine to
set the next prefetch request to the size of nb_pkts.
This will assume that next request will ideally will be
of same size.

Fixes: 4bc5ab88dbd6 ("net/dpaa2: fix Tx only mode")

Incorrect wording.
Maybe:

Ideally commit messages shouldn't have personifications 'you/your' etc
But, it is a trivial thing and I leave at your discretion.

The commit message needs to reflect the fact this patch is also fixing 
some debugging logs which has not relation with default queue. Or, the 
patch should be split.

Also, the commit message can be rephrased for grammatical correctness:

"In case DPAA FMAN configuration tool is not availble, the system can 
still work with default queues (1 queue per port)."

set the next prefetch request to the size of nb_pkts.
It assumes that next request would ideally be
of same size.

[dpdk-dev] [PATCH v3 08/16] bus/dpaa: make vdqcr configurable

[Hemant Agrawal]

From: Nipun Gupta <nipun.gupta@nxp.com>

This patch add support for configurable vdqcr exact flag.
This boost the performance, however this can give
side effects for some extra packet fetch. Which has been
taken care in the patch as well.

[dpdk-dev] [PATCH v3 09/16] net/dpaa: support default queue mode

[Hemant Agrawal]

In case DPAA FMAN configuration tool (FMC) is not available,
the system can still work with default queue(1 queue per port).

This patch also fixes some logs related to FQ ids, which were
idetified while testing this support.

The commit message needs to reflect the fact this patch is also fixing some debugging logs which has not relation with default queue. Or, the patch should be split.

Also, the commit message can be rephrased for grammatical correctness:

"In case DPAA FMAN configuration tool is not availble, the system can still work with default queues (1 queue per port)."

[Hemant]  OK

Incorrect wording.
Maybe:
"It assumes that next request would ideally be of same size"

[Hemant] I have taken care of it in v3.

Why an empty statement?

Series applied without last patch (because must be reworked).

This series has a lot of cleanups. Starting from now, I will consider
NXP drivers as mature enough. I won't accept anymore such patch without
(or not enough) explanation.
For your users and readers, please start considering to explain
what was wrong and what needs to be changed.
Thanks

Its just a way of collating the cases without deep cascade. If we don't 
do this, it would just mean having multiple if cases - either cascading 
or segregated (non if-else). Either way achieves same result.

As for this, it would be because of another patch on master: ab3ce1e0c19 
which was not factored when the tree was reviewed. So, this is a merge 
conflict. Or, maybe a rebase on an old tree before posting patches.

Also, for your comment in [1] - this patch doesn't really need a context 
- it is a feature and the headline is self-explanatory for that.
