Hi,

FYI, your patch has been queued to stable release 19.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before December 10th 2021. 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/cpaelzer/dpdk-stable-queue

Subject: [PATCH] net/i40e/base: fix PF reset

[ upstream commit 25829b55b463f7bb0b69af0e63b19121a16d2a63 ]

PF has to delete all the filters during reset.
If it is fully loaded with filters then it is possible that it will take
more than 200 ms to finish the reset resulting in timeout during pf_reset
and PF reset failed, -15 error indication.

Increasing the timeout value for PF reset from 200 to 1000 to give PF
more time to finish reset if it is loaded with filters.

Fixes: 1e32378f0774 ("i40e/base: increase PF reset max loop limit")
