Hi,

FYI, your patch has been queued to stable release 20.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/24/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/035d9a8422e0f1a00fda7bfc8503efe7bbf08966

Thanks.

Luca Boccassi

Subject: [PATCH] net/ixgbevf: fix promiscuous and allmulti

[ upstream commit 21e471abb548f91190479c75da0c28ebc25dec36 ]

The configuration of allmulti and promiscuous modes conflicts
together. For instance, if we enable promiscuous mode, then enable and
disable allmulti, then the promiscuous mode is wrongly disabled.

Fix this behavior by:
- doing nothing when we set/unset allmulti if promiscuous mode is on
- restorting the proper mode (none or allmulti) when we disable
  promiscuous mode

Fixes: 1f4564ed7696 ("net/ixgbevf: enable promiscuous mode")
