[dpdk-stable] patch 'log/linux: make default output stderr' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/12/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/d43987787c0257694974864963d8b420ee4f89dd

Thanks.

Subject: [PATCH] log/linux: make default output stderr
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 5988725d0efeb7021670986aafeb3ff3d87839e1 ]

In Linux by default DPDK log goes to stdout, as well as syslog.

It is possible for an application to change the library output stream
via 'rte_openlog_stream()' API, to set it to stderr, it can be used as:
rte_openlog_stream(stderr);

But still updating the default log output to 'stderr'.

Bugzilla ID: 8
Fixes: af75078fece3 ("first public release")
