[dpdk-stable] patch 'net/bnxt: fix Rx VLAN offload flags' has been queued to LTS release 18.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/01/19. 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 can be viewed on the 18.11 branch at:
	https://github.com/kevintraynor/dpdk-stable-queue.git

Thanks.

Kevin Traynor

Subject: [PATCH] net/bnxt: fix Rx VLAN offload flags

[ upstream commit 4339de851e55364d0f1f995babaa0006968870c0 ]

The bnxt driver is not correctly setting the receive VLAN offload
flags.  When VLAN is offloaded the driver must set the
PKT_RX_VLAN_STRIPPED flag.

Actually, several drivers have the same bug, only most of the
Intel drivers look right. Any driver that sets vlan_tci is probably
stripping the tag, and should be setting RX_VLAN_STRIPPED.

To quote rte_mbuf.h:

/**
 * The RX packet is a 802.1q VLAN packet, and the tci has been
 * saved in in mbuf->vlan_tci.
 * If the flag PKT_RX_VLAN_STRIPPED is also present, the VLAN
 * header has been stripped from mbuf data, else it is still
 * present.
 */

Fixes: 2eb53b134aae ("net/bnxt: add initial Rx code")
