From mboxrd@z Thu Jan 1 00:00:00 1970 From: Fan Du Subject: [PATCH RFC 2/5] {pktgen, xfrm} Using "pgset spi xxx" to spedifiy SA for a given flow Date: Thu, 5 Dec 2013 15:57:16 +0800 Message-ID: <1386230239-31860-3-git-send-email-fan.du@windriver.com> References: <1386230239-31860-1-git-send-email-fan.du@windriver.com> Mime-Version: 1.0 Content-Type: text/plain Cc: To: , Return-path: Received: from mail.windriver.com ([147.11.1.11]:62067 "EHLO mail.windriver.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752339Ab3LEH51 (ORCPT ); Thu, 5 Dec 2013 02:57:27 -0500 In-Reply-To: <1386230239-31860-1-git-send-email-fan.du@windriver.com> Sender: netdev-owner@vger.kernel.org List-ID: User could set specific SPI value to arm pktgen flow with IPsec transformation, instead of looking up SA by sadr/daddr. The reaseon to do so is because current state lookup scheme is both slow and, most important of all, in fact pktgen doesn't need to match any SA state addresses information, all it needs is the SA transfromation shell to do the encapuslation.
