[dpdk-stable] patch 'net/bnxt: fix single PF per port check' has been queued to stable release 19.11.9

[Christian Ehrhardt]

Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/19/21. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/142c92f25f5d67081e8fd9022089f111b4e982bc

Thanks.

Subject: [PATCH] net/bnxt: fix single PF per port check

[ upstream commit 7712a39cc4e8cc677da47c53e90e1b4d0fce7826 ]

The check BNXT_SINGLE_PF(bp) returns false for a VF. So there is no
extra check needed for VF along with BNXT_SINGLE_PF(bp).

Also make error messages more explicit.

Fixes: ff947c6ce15f ("net/bnxt: add check for multi host PF per port")
Fixes: f86febfb46da ("net/bnxt: support VF")
Fixes: 3e12fdb78e82 ("net/bnxt: support VLAN pvid")
