[dpdk-stable] patch 'eal/freebsd: fix config creation' has been queued to LTS release 18.11.3

[Kevin Traynor]

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 09/03/19. 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/f4a9b2732e8eb2ea126cae8cdf28c8b868d94a00

Thanks.

Kevin Traynor

Subject: [PATCH] eal/freebsd: fix config creation

[ upstream commit e6d3c09282d88e904e4255a0c81e0c19a92217c1 ]

The config create function did not store the mem config address in
the shared memconfig structure, so the secondary processes couldn't
map it at the required address.

Fixes: b149a7064261 ("eal/freebsd: add config reattach in secondary process")
