Subject: [dpdk-dev] [PATCH 0/X v5 02/14] pmd: Add PMD_REGISTER_DRIVER macro
Date: Mon, 21 Apr 2014 10:59:27 -0400	[thread overview]
Message-ID: <1398092379-7679-3-git-send-email-nhorman@tuxdriver.com> (raw)
In-Reply-To: <1398092379-7679-1-git-send-email-nhorman@tuxdriver.com>

Rather than have each driver have to remember to add a constructor to it to make
sure its gets registered properly, wrap that process up in a macro to make
registration a one line affair.  This also sets the stage for us to make
registration of vdev pmds and physical pmds a uniform process
