[dpdk-stable] patch 'net/i40e: fix X722 performance' has been queued to stable release 19.11.3

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/21/20. 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: fix X722 performance

[ upstream commit b4668579286c56fded2816602e104abbcf0b5adb ]

Lack of GL_SWR_PM_UP_THR value for mac type 4x10G X722 caused it can't
reach line rate in one queue one core forwarding case. It's about 1%
performance drop.  This patch adds value as:

 Device-ID  Value        Comments
 0x37D0    0x03030303   4x10G FPK

This value is hardware specific.

Fixes: 3320d4a240da ("net/i40e: workaround performance degradation")
