Hi,

FYI, your patch has been queued to stable release 19.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/11/20. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/d800f1ad66c56eea3cddc51e0a42d092315cf8ab

Thanks.

Subject: [PATCH] net/bnxt: increase size of Rx CQ

[ upstream commit 45c6e1c66a4b5d7374e864502dc2fdb1ee71ceae ]

LRO aka TPA and jumbo frame support uses aggregation ring for placing
Rx buffers. These features can generate multiple Rx completions for a
single Rx packet. Increase size of Rx Completion Queue to handle TPA
and aggregation ring events.

Fixes: daef48efe5e5 ("net/bnxt: support set MTU")
