Subject: [dpdk-dev] [PATCH 2/2] i40e: enable internal switch of pf
Date: Thu, 29 Jan 2015 09:41:55 +0800 [thread overview]
Message-ID: <1422495715-6450-3-git-send-email-jingjing.wu@intel.com> (raw)
In-Reply-To: <1422495715-6450-1-git-send-email-jingjing.wu@intel.com>
This patch enables PF's internal switch by setting ALLOWLOOPBACK
flag when VEB is created. With this patch, traffic from PF can be
switched on the VEB.
