Unfortunately the packet scheduler sits between the hard_header() call (via neigh_*_output() --> dev_hard_header()) and when the device xmit method is invoked. And the packet scheduler can make use of the skb->cb[], for include/net/sch_generic.h:qdisc_skb_cb -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
