From mboxrd@z Thu Jan 1 00:00:00 1970 From: Casey Leedom Subject: [PATCH 02/10] cxgb4vf: don't implement trivial (and incorrect) ndo_select_queue() Date: Wed, 10 Nov 2010 18:04:04 -0800 Message-ID: <1289441052-4925-2-git-send-email-leedom@chelsio.com> References: <450C6E98-D0D9-42A6-9F15-4DB98647DB04@chelsio.com> Cc: davem@davemloft.net, Casey Leedom To: netdev@vger.kernel.org Return-path: Received: from stargate.chelsio.com ([67.207.112.58]:19117 "EHLO stargate.chelsio.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S932224Ab0KKCET (ORCPT ); Wed, 10 Nov 2010 21:04:19 -0500 In-Reply-To: <450C6E98-D0D9-42A6-9F15-4DB98647DB04@chelsio.com> Sender: netdev-owner@vger.kernel.org List-ID: Don't implement (struct net_device_ops *)->ndo_select_queue() with simple call to skb_tx_hash(). This leads to non-persistent TX queue selection in the Linux dev_pick_tx() routine for TCP connections.
