Subject: [dpdk-dev] [PATCH 3/5] examples/vhost: enable promisc mode and config VMDQ offload register for multicast feature
Date: Mon, 25 Aug 2014 10:09:30 +0800
Message-ID: <1408932572-10343-4-git-send-email-changchun.ouyang@intel.com> (raw)
In-Reply-To: <1408932572-10343-1-git-send-email-changchun.ouyang@intel.com>

This patch is to let vhost receive and forward multicast and broadcast packets,
add promiscuous option into command line; and set VMDQ RX mode as:
ETH_VMDQ_ACCEPT_BROADCAST|ETH_VMDQ_ACCEPT_MULTICAST if promisc mode is on.
