[dpdk-stable] patch 'eal/freebsd: ignore in-memory option' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/12/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/341804051a43c954a195b11163529eda40f27063

Thanks.

Subject: [PATCH] eal/freebsd: ignore in-memory option
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 0faa4cfc50275751a86ed17147175c78a36f0da2 ]

The in-memory option is not supported on FreeBSD so print a warning and
ignore the flag when it is specified for BSD apps. The lack of support
is due to the different way in which memory is managed on FreeBSD using
the contigmem driver rather than via a hugetlbfs filesystem.

Fixes: 14de8734c401 ("eal: add --in-memory option")
