Hi,

FYI, your patch has been queued to stable release 20.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/11/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/63e152d10758a6eae614f9d39ade06f24fcdf0d1

Thanks.

Luca Boccassi

Subject: [PATCH] net/pcap: fix byte stats for drop Tx

[ upstream commit cec222d6e55d9bd15eff7fbbf45464c0c6a941c0 ]

Drop Tx path in pcap is Tx that just drops the packets, which is used
for the case only Rx from a pcap file is requested/matters.

The byte stats was calculated using first mbuf segment, which gives
wrong values for multi segmented mbufs, updated to use packet length
instead.

Bugzilla ID: 597
Fixes: a3f5252e5cbd ("net/pcap: enable infinitely Rx a pcap file")
