Message-ID: <4AF99A50.5080301@gmail.com> Date: Tue, 10 Nov 2009 17:52:32 +0100 From: Eric Dumazet <eric.dumazet@...il.com> To: "David S. Miller" <davem@...emloft.net> CC: Herbert Xu <herbert@...dor.apana.org.au>, Linux Netdev List <netdev@...r.kernel.org> Subject: [RFC] vlan: GRO rx statistics It seems vlan interfaces with hardware-assisted VLAN reception dont have rx statistics. Following patch cures the problem for me but I have no idea if it is correct ? Another problem about all rx stats is about multi rx queues devices. Several cpus can access these counters in parallel ? diff --git a/net/8021q/vlan_core.c b/net/8021q/vlan_core.c index 8d5ca2a..e13b007 100644 --- a/net/8021q/vlan_core.c +++ b/net/8021q/vlan_core.c @@ -89,6 +89,11 @@ vlan_gro_common(struct napi_struct *napi, struct vlan_group *grp, if (!skb->dev) goto drop; + skb->dev->stats.rx_packets++; + skb->dev->stats.rx_bytes += skb->len; + if (skb->pkt_type == PACKET_MULTICAST) + skb->dev->stats.multicast++; + for (p = napi->gro_list; p; p = p->next) { NAPI_GRO_CB(p)->same_flow = p->dev == skb->dev && !compare_ether_header( -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
