Sure, it must be somehow\npossible, but that would involve extending SO_TIMESTAMPING yet again,\nand this is not worth the effort, IMHO.\n\nThere is exactly one PHY on the market that supports time stamping,\nand yes, people who design their boards with it generally want to use\nit. They have to enable CONFIG_NETWORK_PHY_TIMESTAMPING and disable\nMAC time stamping.\n\nThanks,\nRichard","headers":{"Return-Path":"","X-Original-To":"patchwork-incoming@ozlabs.org","Delivered-To":"patchwork-incoming@ozlabs.org","Authentication-Results":["ozlabs.org;\n\tspf=none (mailfrom) smtp.mailfrom=vger.kernel.org\n\t(client-ip=209.132.180.67; helo=vger.kernel.org;\n\tenvelope-from=netdev-owner@vger.kernel.org;\n\treceiver=)","ozlabs.org; dkim=pass (2048-bit key;\n\tunprotected) header.d=gmail.com header.i=@gmail.com\n\theader.b=\"icC7x1ZI\"; dkim-atps=neutral"],"Received":["from vger.kernel.org (vger.kernel.org [209.132.180.67])\n\tby ozlabs.org (Postfix) with ESMTP id 3xnHZR3PGHz9sBZ\n\tfor ;\n\tWed, 6 Sep 2017 18:59:11 +1000 (AEST)","(majordomo@vger.kernel.org) by vger.kernel.org via listexpand\n\tid S1752289AbdIFI7J (ORCPT );\n\tWed, 6 Sep 2017 04:59:09 -0400","from mail-wr0-f194.google.com ([209.85.128.194]:35530 \"EHLO\n\tmail-wr0-f194.google.com\" rhost-flags-OK-OK-OK-OK) by vger.kernel.org\n\twith ESMTP id S1752066AbdIFI7G (ORCPT\n\t); Wed, 6 Sep 2017 04:59:06 -0400","by mail-wr0-f194.google.com with SMTP id a47so2782962wra.2;\n\tWed, 06 Sep 2017 01:59:05 -0700 (PDT)","from localhost (213-225-35-115.nat.highway.a1.net.\n\t[213.225.35.115]) by smtp.gmail.com with ESMTPSA id\n\tj15sm1629441wre.87.2017.09.06.01.59.03\n\t(version=TLS1_2 cipher=ECDHE-RSA-CHACHA20-POLY1305 bits=256/256);\n\tWed, 06 Sep 2017 01:59:04 -0700 (PDT)"],"DKIM-Signature":"v=1; a=rsa-sha256; c=relaxed/relaxed;\n\td=gmail.com; s=20161025;\n\th=date:from:to:cc:subject:message-id:references:mime-version\n\t:content-disposition:in-reply-to:user-agent;\n\tbh=kKmfF11fL2c6x9V7Ll3C+bcdk2NhLKZ1ScJZDC/DW4c=;\n\tb=icC7x1ZIlvnNrZFEA2guyqHlemeTkQxM0CLuI0JKxS6mkLY2KruEkwwKUSYiXvHRE4\n\tTGe+WEpyUnO1F4r4Qqa5Oz1pMYrLG2kxRGPFpI/djyhtpWw88uTKBZhRjjZdiQ0m+qjL\n\twWRxxOok+z35ZvcBAzRImHh0K9Opq1E07Mmx0PWYb+Je394Rq34jn0fThHoI9YPup8wk\n\tFRCYst824wUtwukYHsK9C949EEETlGcbTR3xX5NbRkoi6hPLRBkOZR8ueG2XIrO/FR/Q\n\tBf4Y4SVJxDjL3VO2tUlC3Bq1LLTfdhXEqzjAyOvaXD6U6zmgpaM0NcabuN2m39xaVyRC\n\t+crw==","X-Google-DKIM-Signature":"v=1; a=rsa-sha256; c=relaxed/relaxed;\n\td=1e100.net; s=20161025;\n\th=x-gm-message-state:date:from:to:cc:subject:message-id:references\n\t:mime-version:content-disposition:in-reply-to:user-agent;\n\tbh=kKmfF11fL2c6x9V7Ll3C+bcdk2NhLKZ1ScJZDC/DW4c=;\n\tb=qRV58/Ff0xox/HHeJWAv5aVdSIVlhX1xFPapc5IEyVOGYc+QGlRAwbZ1XrHXwoxynZ\n\t77dWoplXai+Gn59+jXdLNjvEA9frzHeUXtwQ73pIvUX5KijtwXvlv48FldXSwJq9mCPb\n\tCf2FN8vGf5xmpTdrJzeGCDjK4zqvnNBeBLqhVXvzEHQ0OpG1e1BPBD2YPD+JI5O+fIJv\n\tavvvr+n9mR6AFEoSYjRcmfhtcYqqKcMFBzcBBfO1rwnfVTnIbdsPPdct4fDkzDEzRYWz\n\tgQWMLleyAOWpwU1PqD178ZqLi2QEZMUmygbtoOHe8Xnk4TOCrx6RPWfFvwSIiwfQm4z7\n\tFOCA==","X-Gm-Message-State":"AHPjjUh3SaL9bUQyGJ5FpffG4HpnuMhLOGbyuuoK5796BYy7olwdOj+6\n\tjTvo/LhAbsq3Zw==","X-Google-Smtp-Source":"ADKCNb6JS/9qaaoj6n5+G8IATepeJMk1V9djLN5F6h0GVK1f3vXlsIan2lz6y0yiJyKjtoKFuu2DGg==","X-Received":"by 10.223.195.108 with SMTP id e41mr1260404wrg.51.1504688345133; \n\tWed, 06 Sep 2017 01:59:05 -0700 (PDT)","Date":"Wed, 6 Sep 2017 10:59:01 +0200","From":"Richard Cochran ","To":"Grygorii Strashko ","Cc":"David Miller ,\n\tstefan.sorensen@spectralink.com, netdev@vger.kernel.org,\n\tlinux-omap@vger.kernel.org","Subject":"Re: [PATCH net-next] net: cpsw: Don't handle SIOC[GS]HWTSTAMP when\n\tCPTS is disabled","Message-ID":"<20170906085901.qauya3ogfewjcyv3@localhost>","References":"<20170830065055.419-1-stefan.sorensen@spectralink.com>\n\t<20170830.144745.947488279115809130.davem@davemloft.net>\n\t<20170831074807.3dbbt6qhqxdquipa@localhost>\n\t","MIME-Version":"1.0","Content-Type":"text/plain; charset=us-ascii","Content-Disposition":"inline","In-Reply-To":"","User-Agent":"NeoMutt/20170113 (1.7.2)","Sender":"netdev-owner@vger.kernel.org","Precedence":"bulk","List-ID":"","X-Mailing-List":"netdev@vger.kernel.org"}}]
