[dpdk-stable] patch 'net/ice: fix disabling promiscuous mode' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/12/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/abb66bf463983bf8434f2af99db8da62d905ce00

Thanks.

Subject: [PATCH] net/ice: fix disabling promiscuous mode
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit fa1d598844a73765cf26676ce3d219589ba57114 ]

When promiscuous mode is disabled, allmulticast is
also disabled, even if it was previously enabled.

Add a test in ice_promisc_disable()
to check if allmulticast should be kept enabled.

Fixes: c945e4bf9063 ("net/ice: support promiscuous mode")
