Date: Thu, 27 Mar 2014 16:34:59 +0100 From: Daniel Borkmann <dborkman@...hat.com> To: davem@...emloft.net Cc: netdev@...r.kernel.org Subject: [PATCH net-next] net: nlmon: flag nlmon devs with LLTX/SG 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.
