Subject: net/ark: fix leak on thread termination
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b8b5dc6b9596a07cbeed03192b41a4befb75acc6;p=dpdk.git

net/ark: fix leak on thread termination

A terminated pthread should be joined or detached so that its associated
resources are released.

The "ark-delay-pg" thread is just used to delay some task but it is never
joined by the thread that created it.
The easiest solution is to detach the new thread.
