Subject: [dpdk-dev] [PATCH 5/7] pci: Move driver registration above pci scan
Date: Wed, 23 Nov 2016 12:36:42 -0700	[thread overview]
Message-ID: <1479929804-19614-6-git-send-email-benjamin.walker@intel.com> (raw)
In-Reply-To: <1479929804-19614-1-git-send-email-benjamin.walker@intel.com>

The user needs to register drivers before scanning, so
it makes the most sense to put the registration
functions above the scan function in the header file.
