Subject: [dpdk-dev] [PATCH v4 09/10] examples/l3fwd-power: add parse-ptype option
Date: Tue, 17 Jan 2017 07:10:29 +0000 [thread overview]
Message-ID: <1484637030-106261-10-git-send-email-jianfeng.tan@intel.com> (raw)
In-Reply-To: <1484637030-106261-1-git-send-email-jianfeng.tan@intel.com>
To support those devices that do not provide packet type info when
receiving packets, add a new option, --parse-ptype, to analyze
packet type in the Rx callback.
Signed-off-by: Jianfeng Tan <jianfeng.tan@intel.com>
