| |
hi all,
this code excerpt from net_rx_action in dev.c does not get executed at all. is there any need for it? what does it do?
i inserted printk's in it just about everywhere. i have a test network set up, A talks to C via router B (kernel 2.4.14) justificattion: i've pinged C from A, I've pinged eth0 on B from A,I've pinged eth1 on B from A and i've pinged A from router B and in no instance was any of the following code executed.
whats CONFIG_NET_FASTROUTE supposed to do?
the only part that does get executed are the lines: "skb->h.raw = skb->nh.raw = skb->data; {struct packet_type *ptype, *pt_prev; unsigned short type = skb->protocol; pt_prev = NULL;" just after the CONFIG_NET_FASTROUTE section of code.
#ifdef CONFIG_NET_FASTROUTE if (skb->pkt_type == PACKET_FASTROUTE) { netdev_rx_stat[this_cpu].fastroute_deferred_out++; dev_queue_xmit(skb); dev_put(rx_dev); continue; } #endif skb->h.raw = skb->nh.raw = skb->data; {
struct packet_type *ptype, *pt_prev; unsigned short type = skb->protocol;
pt_prev = NULL; for (ptype = ptype_all; ptype; ptype = ptype->next) { if (!ptype->dev || ptype->dev == skb->dev) { if (pt_prev) { if (!pt_prev->data) { deliver_to_old_ones(pt_prev, skb, 0); } else { atomic_inc(&skb->users); pt_prev->func(skb, skb->dev, pt_prev); } } pt_prev = ptype; } }
#ifdef CONFIG_NET_DIVERT if (skb->dev->divert && skb->dev->divert->divert) handle_diverter(skb); #endif /* CONFIG_NET_DIVERT */
#if defined(CONFIG_BRIDGE) || defined(CONFIG_BRIDGE_MODULE) if (skb->dev->br_port != NULL && br_handle_frame_hook != NULL) { handle_bridge(skb, pt_prev); dev_put(rx_dev); continue; } #endif
if i'm wrong let me know, thanks.
