Subject: [dpdk-dev] [PATCH v2 24/25] ethdev: reset all when releasing a port
Date: Mon, 28 Sep 2020 01:42:48 +0200
Message-ID: <20200927234249.3198780-25-thomas@monjalon.net> (raw)
In-Reply-To: <20200927234249.3198780-1-thomas@monjalon.net>

The function rte_eth_dev_release_port() was resetting partially
the struct rte_eth_dev. The drivers were completing it
with more pointers set to NULL in the close or remove operations.

A full memset is done so most of those assignments become useless.
