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 07/14/22. 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/9224015451386fc4e45195fd057f0a5d22fb5eba

Thanks.

Luca Boccassi

Subject: [PATCH] examples/link_status_interrupt: fix stats refresh rate

[ upstream commit 14d460b888c290e16c00cff4ae809d14fe799aec ]

TIMER_MILLISECOND is defined as the number of CPU cycles per millisecond.
The current definition is correct only for cores with frequency of 2GHz.

Use DPDK API to get CPU frequency, and to define timer period.

Fixes: af75078fece3 ("first public release")
