From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rasesh Mody Subject: [PATCH 60/61] net/qede: add ntuple and flow director filter support Date: Sun, 26 Feb 2017 23:57:16 -0800 Message-ID: <1488182237-10247-61-git-send-email-rasesh.mody@cavium.com> References: <1488182237-10247-1-git-send-email-rasesh.mody@cavium.com> Mime-Version: 1.0 Content-Type: text/plain Cc: Harish Patil , To: Return-path: Received: from mx0b-0016ce01.pphosted.com (mx0b-0016ce01.pphosted.com [67.231.156.153]) by dpdk.org (Postfix) with ESMTP id 50FD8FA51 for ; Mon, 27 Feb 2017 08:58:46 +0100 (CET) In-Reply-To: <1488182237-10247-1-git-send-email-rasesh.mody@cavium.com> List-Id: DPDK patches and discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces@dpdk.org Sender: "dev" From: Harish Patil Add limited support for ntuple filter and flow director configuration. The filtering is based on 4-tuples viz src-ip, dst-ip, src-port, dst-port. The mask fields, tcp_flags, flex masks, priority fields, Rx queue drop etc are not supported.
