[dpdk-stable] patch 'net/bnxt: refactor multi-queue Rx configuration' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/21. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/699e70a0b61347f8f9f6d2e2366f1a75dc05118c

Thanks.

Subject: [PATCH] net/bnxt: refactor multi-queue Rx configuration
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 21b1677d87a23a9695be0cbcbdf38607a2d58f84 ]

Eliminate separate codepath/handling for single queue
as the multiqueue code path takes care of it as well.
The only difference being the end_grp_id being 1
now instead of 0 for single queue, but that does not matter
for single queue and does not alter any functionality.

Fixes: 6133f207970c ("net/bnxt: add Rx queue create/destroy")
