Subject: [dpdk-dev] [PATCH v2 4/8] eal: cleanup threads
Date: Tue, 28 Apr 2020 16:14:11 -0700
Message-ID: <20200428231415.17985-5-stephen@networkplumber.org> (raw)
In-Reply-To: <20200428231415.17985-1-stephen@networkplumber.org>

When rte_eal_cleanup is called it should stop all the child threads
and close the pipes between threads.
