[dpdk-stable] patch 'net/avf: fix releasing mbufs' has been queued to LTS release 18.11.11

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/27/20. 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.

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/67ae38570c4e8b3c14d781e09eba210179342f8a

Thanks.

Kevin.

Subject: [PATCH] net/avf: fix releasing mbufs

[ upstream commit 36b8b062885f2b6576818a1c18ffaacb4dccefa5 ]

In the function _avf_rx_queue_release_mbufs_vec to release rx mbufs,
rxq->rxrearm_nb is given the value of rx descriptor number at last.
However, since the process to release and allocate mbufs lacks the
initialization of rxrearm_nb, if we try to release mbufs next time, it
will return without releasing directly. In this patch, rxrearm_nb is
initialized to be zero in rx queue reset.

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