[dpdk-stable] patch 'net/ice: fix queue MSI-X interrupt binding' has been queued to stable release 19.11.1

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/29/20. 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.

Thanks.

Luca Boccassi

Subject: [PATCH] net/ice: fix queue MSI-X interrupt binding

[ upstream commit 8b0add355f4a38aefc272c995b949f1fe6f1a512 ]

Operator '<<' should be used instead of '<' for shifting value to be
set in MSI-X configuration register.

Old code adds 1 on even MSI-X interrupt vector index used by queue,
resulting in interrupt mapping error.

Fixes: 65dfc889d86b ("net/ice: support Rx queue interruption")
