[dpdk-stable] patch 'net/tap: fix interrupt vector array size' 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 06/14/21. 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/58155c9ecf43f1774cbedc0e04b1739b2101065e

Thanks.

Subject: [PATCH] net/tap: fix interrupt vector array size
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 2ce7bc96344542f8d3e89b41bbaaafb12e1d9f72 ]

The size of the current interrupt vector array is fixed to an integer.

This patch will create an interrupt vector array based on the number
of rxqs.

Fixes: 4870a8cdd968 ("net/tap: support Rx interrupt")
