Hi, I'm a little bit bothered because of those inner_ functions, what about the following approach: 1. the skb will have a new state, that state can be outer (normal mode) and inner. 2. when you change the state to inner, all the helper functions such as ip_hdr will return the innter header. that's ofcourse the API side. the implementation may still use the fields you added to the skb. what you think? saeed -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
