From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sreenivasa Honnur Subject: [net-next-2.6 PATCH 1/9] vxge: Modify __vxge_hw_device_is_privilaged() to not assume function-0 as the privileged function: Resubmit#1 Date: Mon, 5 Oct 2009 07:51:38 -0400 (EDT) Message-ID: Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Cc: netdev@vger.kernel.org, support@neterion.com To: davem@davemloft.net Return-path: Received: from barracuda.s2io.com ([72.1.205.138]:42021 "EHLO barracuda.s2io.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1758493AbZJEL7R (ORCPT ); Mon, 5 Oct 2009 07:59:17 -0400 Sender: netdev-owner@vger.kernel.org List-ID: - vxge driver was assuming function-0 is always the privilaged function. Now that restriction has been removed any function can act as a privilaged function. - This patch modifies the __vxge_hw_device_is_privilaged routine to not assume function-0 as the privileged function. - Recreated the patch by incorporating review comments from Dave Miller to remove double slash in path names.
