From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from mx1.redhat.com ([209.132.183.28]:43980 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751174AbbCTS2B (ORCPT ); Fri, 20 Mar 2015 14:28:01 -0400 Subject: [PATCH] PCI: Add ACS quirks for Intel 1G NICs From: Alex Williamson To: bhelgaas@google.com, linux-pci@vger.kernel.org Cc: john.ronciak@intel.com, linux-kernel@vger.kernel.org Date: Fri, 20 Mar 2015 12:27:57 -0600 Message-ID: <20150320182722.5362.75868.stgit@gimli.home> MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Sender: linux-pci-owner@vger.kernel.org List-ID: Intel has verified that there is no peer-to-peer between functions for the below selection of 82580, 82576, 82575, I350, and 82571 multi-port devices. This adds the necessary quirks to consider the functions isolated from each other. 82571 quad-port devices are omitted due to likely lack of ACS/isolation in the onboard switch, rendering quirks for the downstream endpoints useless.
