[dpdk-dev] [PATCH] telemetry: detach pthreads

[dpdk-dev] [PATCH] telemetry: detach pthreads

[Stephen Hemminger]

There are a number telemetry threads which are created and
there is nothing that does pthread_join() to wait for them.
Mark these threads as detached, so that the pthread library
can cleanup state when the thread exits.
