[dpdk-stable] patch 'net/i40e: fix port close in FreeBSD' has been queued to stable release 19.11.1

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/13/20. 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.

Thanks.

Luca Boccassi

Subject: [PATCH] net/i40e: fix port close in FreeBSD

[ upstream commit 1fa41f4518f9f30465a0ed32640e7dbce00b3f4f ]

FreeBSD OS doesn't support igb_uio interrupt, so it will fail when
unregister the interrupt callback in port close. We can fix the issue by
passing -ENOENT when check the return value of unregister interrupt
callback function.

Fixes: ac89d46096d5 ("net/i40e: release port upon close")
