[dpdk-stable] patch 'net/ipn3ke: use control thread to check link status' 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/ipn3ke: use control thread to check link status

[ upstream commit e5791726338ea4b83e329fd59e9d1af7066b7c0b ]

ipn3ke driver creates a thread to check link status.

Before this patch, pthread_create() is used to create
thread, leaving the new thread unrestrained wrt cpu
affinity.

After this patch, rte_ctrl_thread_create() is used to
create thread. The affinity of the new thread is based
on the CPU affinity retrieved at the time rte_eal_init()
was called, the dataplane and service lcores are then
excluded.

Fixes: 70d6b7f550f4 ("net/ipn3ke: add representor")
