From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ben Hutchings Subject: [PATCH net-next-2.6 2/2] niu: Recognise original ethtool class code for AH/ESP flow hashing Date: Sat, 09 Apr 2011 00:49:15 +0100 Message-ID: <1302306555.2871.59.camel@bwh-desktop> Mime-Version: 1.0 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 7bit Cc: netdev@vger.kernel.org, Alexander Duyck , Santwona Behera , Jeff Kirsher To: David Miller Return-path: Received: from exchange.solarflare.com ([216.237.3.220]:6453 "EHLO exchange.solarflare.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752482Ab1DHXtT (ORCPT ); Fri, 8 Apr 2011 19:49:19 -0400 Sender: netdev-owner@vger.kernel.org List-ID: When the RX network flow classification interface was originally defined for reporting and controlling of flow hashing, AH and ESP were not given distinct flow class codes (apparently because the Sun Neptune hardware treats them very similarly). For flow steering, they must be distinguished, so new and separate flow class codes were added for AH and ESP. But for backward- compatibility, flow hash operations should continue to support the original class codes.
