From mboxrd@z Thu Jan 1 00:00:00 1970 From: Roopa Prabhu Subject: [net-next-2.6 PATCH] enic: Bug Fix: Dont reset ENIC_SET_APPLIED flag on port profile disassociate Date: Thu, 20 Jan 2011 16:35:54 -0800 Message-ID: <20110121003554.25697.15096.stgit@savbu-pc100.cisco.com> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Cc: netdev@vger.kernel.org To: davem@davemloft.net Return-path: Received: from sj-iport-2.cisco.com ([171.71.176.71]:27395 "EHLO sj-iport-2.cisco.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1753701Ab1AUAfy (ORCPT ); Thu, 20 Jan 2011 19:35:54 -0500 Sender: netdev-owner@vger.kernel.org List-ID: From: Roopa Prabhu enic_get_vf_port returns port profile operation status only if ENIC_SET_APPLIED flag is set. A recent rework of enic_set_port_profile added code to reset this flag on disassociate. As a result of which a client calling enic_get_vf_port to get the status of port profile disassociate will always get a return value of ENODATA. This patch renames ENIC_SET_APPLIED to more appropriate ENIC_PORT_REQUEST_APPLIED and reverts back the recent change so that the flag is set both at associate and disassociate of a port profile.
