patch 'sched: remove unnecessary floating point' has been queued to stable release 21.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/bba01c7ab88dfac1a732b3fb12cf81921bec9da2

Thanks.

Kevin

Subject: [PATCH] sched: remove unnecessary floating point

[ upstream commit bb421e98c0c0f56f1adc68722a54d6d24abf137d ]

The qdelay variable is derived from and compared to 64 bit
value so it doesn't have to be floating point.

Fixes: 44c730b0e379 ("sched: add PIE based congestion management")
