[dpdk-stable] patch 'net/i40e: keep promiscuous on if allmulticast is enabled' has been queued to LTS release 17.11.5

[Yongseok Koh]

Hi,

FYI, your patch has been queued to LTS release 17.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/01/18. 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. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Yongseok

Subject: [PATCH] net/i40e: keep promiscuous on if allmulticast is enabled

[ upstream commit 815037b92b3437754183fb256a967a7e82d3820a ]

Promisc should not be disabled if the all multicast mode is enabled.
Patch keeps the promiscuous on if all multicast mode is on, this
behavior is also consistent with the implementation done on ixgbe
pmd.
