"If a packet is handled by a bridge, that is, a component that does not deal with layer 3 or 4, there is no point in spending time to find the start of the layer 3/4 header." Ok, well: great. but in this case (bridge) also the skb_network_header function is senseless because we don't have to find layer3 header. isn't it? in general: when i can use the skb_transport_header function? -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
