[dpdk-stable] patch 'net/iavf: fix setting L2TAG' has been queued to stable release 19.11.3

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/29/20. 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.

Thanks.

Luca Boccassi

Subject: [PATCH] net/iavf: fix setting L2TAG

[ upstream commit 2482a99f303873175c5781d3c685eaa9e17cfaf7 ]

Base on HW, if a packet is split into multiple segments, the L2TAG
should only be valid on the last Rx descriptor. So fix it by setting
L2TAG into mbuf when processing the last split packet.

Fixes: 319c421f3890 ("net/avf: enable SSE Rx Tx")
