[dpdk-stable] patch 'net: adjust L2 length on soft VLAN insertion' has been queued to LTS release 18.11.3

[Kevin Traynor <ktraynor@redhat.com>]

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/6426f92cf57b3ce5d81497e3d5e3e5eb811452a5

Thanks.

Kevin Traynor

Subject: [PATCH] net: adjust L2 length on soft VLAN insertion

[ upstream commit 42caa11b370e17bdbba498766b0fbad0975d8fa9 ]

Layer 2 length must be updated after the prepend to mbuf to keep
the length right to be used by other Tx offloads.

If the packet has tunnel encapsulation, outer_l2_len should be
updated. Otherwise l2_len should be updated.

Fixes: c974021a5949 ("ether: add soft vlan encap/decap")
