From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Yaniv Rosner" Subject: [PATCH net-2.6 2/8] bnx2x: Common init will be executed only once after POR Date: Tue, 18 Jan 2011 16:33:24 +0200 Message-ID: <1295361204.5281.85.camel@lb-tlvb-dmitry> Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Cc: netdev@vger.kernel.org, eilong@broadcom.com To: davem@davemloft.net Return-path: Received: from mms3.broadcom.com ([216.31.210.19]:3540 "EHLO MMS3.broadcom.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752069Ab1AROcw (ORCPT ); Tue, 18 Jan 2011 09:32:52 -0500 Sender: netdev-owner@vger.kernel.org List-ID: Common init used to be called by the driver when the first port comes up, mainly to reset and reload external PHY microcode. However, in case management driver is active on the other port, traffic would halted. So limit the common init to be done only once after POR.
