[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 09/04/19. 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

Subject: [PATCH] net/i40e: fix flow director rule destroy

[ upstream commit 4fe1af80dd50bc44ac8ff2f395e8584f305b879c ]

We should tear down the fdir when the last flow is destroyed, current
logic is opposite to expected behavior, this patch fixes this issue.

Fixes: 2e67a7fbf3ff ("net/i40e: config flow director automatically")
