So I support to follow this route. \n\nI believe we can create a much smaller correction which just fixes the wire format without adding any support for the new TTL field. That patch could be delivered on the 2.8 maintenance branch.\n\nFull compliance to the final RFC with support for the TTL field, the dec_nsh_ttl action and proper alignment with the net-next kernel datapath uAPI should then be targeted for OVS 2.9.\n\nRegards, Jan","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","dev@openvswitch.org"],"Delivered-To":["patchwork-incoming@bilbo.ozlabs.org","ovs-dev@mail.linuxfoundation.org"],"Authentication-Results":"ozlabs.org;\n\tspf=pass (mailfrom) smtp.mailfrom=openvswitch.org\n\t(client-ip=140.211.169.12;

I think the nsh_ttl match field and the corresponding dec_nsh_ttl action can be left to master.\n\nI already had a small patch series prepared for master and branch-2.8 with the fixes. I will add your initialization of NSH TTL to 63 to it and send out shortly.\n\nBR, Jan","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","dev@openvswitch.org"],"Delivered-To":["patchwork-incoming@bilbo.ozlabs.org","ovs-dev@mail.linuxfoundation.org"],"Authentication-Results":"ozlabs.org;\n\tspf=pass (mailfrom) smtp.mailfrom=openvswitch.org\n\t(client-ip=140.211.169.12; helo=mail.linuxfoundation.org;\n\tenvelope-from=ovs-dev-bounces@openvswitch.org;\n\treceiver=)","Received":["from mail.linuxfoundation.org (mail.linuxfoundation.org\n\t[140.211.169.12])\n\t(using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256\n\tbits)) (No client certificate requested)\n\tby ozlabs.org (Postfix) with ESMTPS id 3yW6c44kPbz9sBZ\n\tfor ;\n\tTue, 7 Nov 2017 09:26:44 +1100 (AEDT)","from mail.linux-foundation.org (localhost [127.0.0.1])\n\tby mail.linuxfoundation.org (Postfix) with ESMTP id ADB28B0B;\n\tMon, 6 Nov 2017 22:26:42 +0000 (UTC)","from smtp1.linuxfoundation.org (smtp1.linux-foundation.org\n\t[172.17.192.35])\n\tby mail.linuxfoundation.org (Postfix) with ESMTPS id EDA05AF3\n\tfor ; Mon, 6 Nov 2017 22:26:41 +0000 (UTC)","from sesbmg23.ericsson.net (sesbmg23.ericsson.net [193.180.251.37])\n\tby smtp1.linuxfoundation.org (Postfix) with ESMTPS id 396D679\n\tfor ; Mon, 6 Nov 2017 22:26:41 +0000 (UTC)","from ESESSHC003.ericsson.se (Unknown_Domain [153.88.183.27])\n\tby sesbmg23.ericsson.net (Symantec Mail Security) with SMTP id\n\tC8.E8.03220.F91E00A5; Mon, 6 Nov 2017 23:26:39 +0100 (CET)","from ESESSMB107.ericsson.se ([169.254.7.134]) by\n\tESESSHC003.ericsson.se ([153.88.183.27]) with mapi id 14.03.0352.000; \n\tMon, 6 Nov 2017 23:26:39 +0100"],"X-Greylist":"domain auto-whitelisted by SQLgrey-1.7.6","X-AuditID":"c1b4fb25-debff70000000c94-2c-5a00e19f8518","From":"Jan Scheurich ","To":"Ben Pfaff , \"Yang, Yi\" ","Thread-Topic":"[PATCH v5 1/2] nsh: add new flow key 'ttl'","Thread-Index":"AQHTIPQi+dq82gHuKUuRIUePh5g18qMAVDSAgAcxFACAAMFHAIAAEjzw","Date":"Mon, 6 Nov 2017 22:26:38 +0000","Message-ID":"","References":"<1504030862-14591-1-git-send-email-yi.y.yang@intel.com>\n\t<1504030862-14591-2-git-send-email-yi.y.yang@intel.com>\n\t<20171101205315.GK27530@ovn.org>\n\t<20171106104244.GA52381@localhost.localdomain>\n\t<20171106221430.GJ27530@ovn.org>","In-Reply-To":"<20171106221430.GJ27530@ovn.org>","Accept-Language":"en-US","Content-Language":"en-US","X-MS-Has-Attach":"","X-MS-TNEF-Correlator":"","x-originating-ip":"[153.88.183.154]","MIME-Version":"1.0","X-Brightmail-Tracker":"H4sIAAAAAAAAA+NgFprJIsWRmVeSWpSXmKPExsUyM2K7tO78hwxRBpsPKVm8mtzAaHH09B5m\n\ti8U9J5gsVmw6zWzx++s2JgdWjyOLDjJ6LN7zksnj2c3/jB7Pr/WweLzfd5UtgDWKyyYlNSez\n\tLLVI3y6BK+PFMZWChzwVX2+dY29gfM3ZxcjJISFgIjG95RNLFyMXh5DAYUaJw/f+skE4ixkl\n\tPrUvZuxi5OBgEzCQmL3bAaRBRMBW4siWXYwgNrNAoUTfuU4wW1jAXGL6iQtsEDUWEuffdbJC\n\t2G4StzuOg9WwCKhILDu8hwVkJK+Ar8THuZoQq74wSsw69JgZpIZTQFfi5pv/YHMYBcQkvp9a\n\twwSxS1zi1pP5TBBHC0gs2XOeGcIWlXj5+B8rhK0ksej2Z6h6HYkFuz+xQdjaEssWvgar5xUQ\n\tlDg58wnLBEbRWUjGzkLSMgtJyywkLQsYWVYxihanFiflphsZ66UWZSYXF+fn6eWllmxiBEbY\n\twS2/VXcwXn7jeIhRgINRiYf31yGGKCHWxLLiytxDjBIczEoivNvVgUK8KYmVValF+fFFpTmp\n\txYcYpTlYlMR5HfddiBASSE8sSc1OTS1ILYLJMnFwSjUwZhQfj5r0THjBpDCZlTLJ8/dM+c55\n\tM2XWq/43xi+6Lea7Nt4XkaqqVwg63Mb+ZuvWvL5ahZK6x7qfFOfUccvv9fqs86JqS8+Fh24L\n\tZnEX8vYqvV905NOVeoW5M10mZQeHzc+cVphV9CJKcNXzkH3rfoYoqadHLTNNF+9b33hgy4l7\n\tRwxX1F3/osRSnJFoqMVcVJwIAJMCcH+sAgAA","X-Spam-Status":"No, score=-2.3 required=5.0 tests=RCVD_IN_DNSWL_MED\n\tautolearn=disabled version=3.3.1","X-Spam-Checker-Version":"SpamAssassin 3.3.1 (2010-03-16) on\n\tsmtp1.linux-foundation.org","Cc":"\"dev@openvswitch.org\" , \"e@erig.me\" ,\n\t\"jbenc@redhat.com\" ","Subject":"Re: [ovs-dev] [PATCH v5 1/2] nsh: add new flow key 'ttl'","X-BeenThere":"ovs-dev@openvswitch.org","X-Mailman-Version":"2.1.12","Precedence":"list","List-Id":"","List-Unsubscribe":",\n\t","List-Archive":"","List-Post":"","List-Help":"","List-Subscribe":",\n\t","Content-Type":"text/plain; charset=\"us-ascii\"","Content-Transfer-Encoding":"7bit","Sender":"ovs-dev-bounces@openvswitch.org","Errors-To":"ovs-dev-bounces@openvswitch.org"}}]
