[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/13/24. 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

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/4a95397cc026929baa39efc6443302b7f84b5d60

Subject: [PATCH] net/ixgbe: increase VF reset timeout

[ upstream commit 64e714f838aeb1afbd4e7544686a0d7cd8921589 ]

When VF issues a reset to PF there is a 50 msec wait plus an additional
max of 1 msec (200 * 5us) for the PF to indicate the reset is complete
before timeout.

In some cases, it is seen that the reset is timing out, in which case
the reset does not complete and an error is returned.

In order to account for this, continue to wait an initial 50 msecs, but
then allow a max of an additional 50 msecs (10,000 * 5us) for the
command to complete.

Fixes: af75078fece3 ("first public release")
