That does seem very promising but while implementing it I hit a problem. struct tcp_skb_cb includes a field of type struct inet6_skb_parm. And expanding struct inet6_skb_parm by 16 bytes means that struct tcp_skb_cb is now larger than 48 bytes and no longer fits in skb->cb. Is it appropriate to grow skb->cb as the comment above struct tcp_skb_cb suggests? -- To unsubscribe from this list: send the line "unsubscribe lvs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
