Subject: [dpdk-dev] [PATCH v5] app/pdump: add pudmp exits with primary support.
Date: Tue, 30 Apr 2019 11:35:24 +0000 [thread overview]
Message-ID: <1556624124-54930-2-git-send-email-mousuanming@huawei.com> (raw)
In-Reply-To: <1556624124-54930-1-git-send-email-mousuanming@huawei.com>
When primary app exits, the residual running pdump will stop the
primary app to restart. Add pdump exits with primary support.
Suggested-by: Varghese, Vipin <vipin.varghese@intel.com>
