Subject: [PATCH net-next] net: nlmon: flag nlmon devs with LLTX/SG
Date: Thu, 27 Mar 2014 16:34:59 +0100 [thread overview]
Message-ID: <1395934499-29092-1-git-send-email-dborkman@redhat.com> (raw)
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.
