Subject: Re: [dts] [PATCH] L3fwd: Add RFC2544 support and able to print loss packets in linerate now.
Date: Thu, 22 Oct 2015 02:41:26 +0000 [thread overview]
Message-ID: <533710CFB86FA344BFBF2D6802E6028621B502EA@SHSMSX101.ccr.corp.intel.com> (raw)
In-Reply-To: <1445479809-5459-1-git-send-email-hengx.ding@intel.com>
You should remove "-P" option, and for RRC, the packet L2 should include
src mac
Thanks,
Michael
