[dpdk-stable] patch 'net/bnxt: save the number of EM flow count' has been queued to LTS release 18.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 09/04/19. 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/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/001848b86710666f4723133a02438adf25bc8590

Thanks.

Kevin Traynor

Subject: [PATCH] net/bnxt: save the number of EM flow count

[ upstream commit ff9c0ca47e81176b5721c0f60dfc411330d205c6 ]

Save the number of EM flow count returned by the FW in HWRM_FUNC_QCFG
and use it to calculate the overall pool of L2 contexts supported by FW.

Fixes: 6d8109bcb398 ("net/bnxt: check VF resources if resource manager is enabled")
