Hi,

FYI, your patch has been queued to stable release 20.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/20/22. 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/2da6c3024762d5b8ef308aaac5ae11a50fe03969

Thanks.

Luca Boccassi

Subject: [PATCH] eal/windows: fix error code for not supported API

[ upstream commit 7e71c4dce375b8aa575dbdcda97936199a4136f3 ]

UT memory_autotest on Windows has 2 failed cases on EAL APIs
eal_memalloc_get_seg_fd and eal_memalloc_get_seg_fd_offset. These 2
APIs are not supported on Windows yet. Should return ENOTSUP such that
in test_memory.c these 2 ENOTSUP cases will not be marked as failures,
same as other ENOTSUP cases.

Fixes: 2a5d547a4a9b ("eal/windows: implement basic memory management")
