From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel Borkmann Subject: [PATCH net-next] net: nlmon: flag nlmon devs with LLTX/SG Date: Thu, 27 Mar 2014 16:34:59 +0100 Message-ID: <1395934499-29092-1-git-send-email-dborkman@redhat.com> Cc: netdev@vger.kernel.org To: davem@davemloft.net Return-path: Received: from mx1.redhat.com ([209.132.183.28]:35577 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1753943AbaC0PfC (ORCPT ); Thu, 27 Mar 2014 11:35:02 -0400 Sender: netdev-owner@vger.kernel.org List-ID: As in xmit path we merely update statistics and free the skb, we can mark the device with LLTX feature, so that upper layers can avoid taking the single txq lock on xmit. While at it, also add missing NETIF_F_SG.
