From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ben Dooks Subject: [patch 3/3] KS8851: Fix ks8851_set_rx_mode() for IFF_MULTICAST Date: Tue, 20 Oct 2009 10:49:05 +0100 Message-ID: <20091020094954.578325358@fluff.org.uk> References: <20091020094902.274646871@fluff.org.uk> Cc: Ping.Doong@Micrel.Com To: netdev@vger.kernel.org Return-path: Received: from aeryn.fluff.org.uk ([87.194.8.8]:50625 "EHLO kira.home.fluff.org" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S1751740AbZJTJtw (ORCPT ); Tue, 20 Oct 2009 05:49:52 -0400 Content-Disposition: inline; filename=ks8851-fix-mc-rxmode.patch Sender: netdev-owner@vger.kernel.org List-ID: In ks8851_set_rx_mode() the case handling IFF_MULTICAST was also setting the RXCR1_AE bit by accident. This meant that all unicast frames where being accepted by the device. Remove RXCR1_AE from this case. Note, RXCR1_AE was also masking a problem with setting the MAC address properly, so needs to be applied after fixing the MAC write order. Fixes a bug reported by Doong, Ping of Micrel. This version of the patch avoids setting RXCR1_ME for all cases.
