From: Declan Doherty <declan.doherty@intel.com> To: dev@dpdk.org Subject: [dpdk-dev] [PATCH v4 3/6] EAL support for link bonding device initialization Date: Mon, 16 Jun 2014 12:18:30 +0100 Message-ID: <1402917513-19495-4-git-send-email-declan.doherty@intel.com> (raw) In-Reply-To: <cover.1402662300.git.declan.doherty@intel.com> Updating functionality in EAL to support adding link bonding devices via –vdev option. Link bonding devices will be initialized after all physical devices have been probed and initialized.
