From mboxrd@z Thu Jan 1 00:00:00 1970 From: Vlad Yasevich Subject: [PATCH net] bonding: Don't assume 802.1Q when sending alb learning packets. Date: Wed, 21 May 2014 11:24:39 -0400 Message-ID: <1400685879-21843-1-git-send-email-vyasevic@redhat.com> Cc: Vlad Yasevich , Jay Vosburgh , Veaceslav Falico , Andy Gospodarek To: netdev@vger.kernel.org Return-path: Received: from mx1.redhat.com ([209.132.183.28]:63201 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752648AbaEUPYq (ORCPT ); Wed, 21 May 2014 11:24:46 -0400 Sender: netdev-owner@vger.kernel.org List-ID: TLB/ALB learning packets always assume 802.1Q vlan protocol, but that is no longer the case since we now have support for Q-in-Q on top of bonding. Pass the vlan protocol to alb_send_lp_vid() so that the packets are properly tagged.
