[dpdk-stable] patch 'net/i40e/base: fix Tx descriptors number' 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 02/13/20. 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/i40e/base: fix Tx descriptors number

[ upstream commit 79bfe7808788c8a9fb7be87cb864dba2bcbab80d ]

The existing driver allows setting the number of TX descriptors
to the value that is indivisible by 32. This is not properly
supported by x710 hardware. The patch limits the number of TX
descriptors to the whole value of 32.

Fixes: 8db9e2a1b232 ("i40e: base driver")
