[dpdk-stable] patch 'net/bnxt: fix VLAN add when port is stopped' has been queued to LTS release 18.11.9

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to LTS release 18.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/03/20. 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/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/56090ed8eab43f2a4319d098aa89baec60f60817

Thanks.

Kevin.

Subject: [PATCH] net/bnxt: fix VLAN add when port is stopped

[ upstream commit 8b60154d4b8a413eec43aafce1b4341dd575d4c3 ]

Driver destroys the vnic when the port is brought down.
When user tries to add a vlan when port is stopped, driver
issues HWRM command to FW with invalid vnic_id and it fails.

Fixed to return an error while setting vlan when port is
not started.

Fixes: b4e190d55c25 ("net/bnxt: fix MAC/VLAN filter allocation")
