[dpdk-stable] patch 'net/null: fix multi-process Rx and Tx' has been queued to LTS release 18.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/10/19. 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/74677ac9c49816a7fbd81f8f0aad753dee504216

Thanks.

Kevin.

Subject: [PATCH] net/null: fix multi-process Rx and Tx

[ upstream commit bccc77a6a74a6c30e68f88b2ef0d0099c45898c8 ]

Packet processing in secondary process cannot work because rx_pkt_burst
and tx_pkt_burst in eth_dev are not initialized while probing device.
This patch is to the initialization.

Fixes: ee27edbe0c10 ("drivers/net: share vdev data to secondary process")
