Subject: [dpdk-dev] [PATCH v11 2/2] librte_pmd_null: Support port hotplug function
Date: Mon, 23 Feb 2015 14:12:35 +0900
Message-ID: <1424668355-8794-2-git-send-email-mukawa@igel.co.jp> (raw)
In-Reply-To: <1424668355-8794-1-git-send-email-mukawa@igel.co.jp>

This patch adds port hotplug support to Null PMD.

v9:
 - Use rte_eth_dev_release_port() instead of rte_eth_dev_free().
v7:
 - Add parameter checkings.
   (Thanks to Iremonger, Bernard)
v6:
 - Fix a parameter of rte_eth_dev_free().
v4:
 - Fix commit title.
