From b7d47ca2fdfd3b613b800c923553a8437dd8da40 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Thu, 27 Mar 2014 16:34:59 +0100 Subject: [PATCH] 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. Signed-off-by: Daniel Borkmann Acked-by: Eric Dumazet Signed-off-by: David S.
