I do and have strange arp problems. When my default gateway is down
and the local lan is idle for a while and I then attempt an arp
to a host on my local lan (not the gateway) the arp never gets
sent on the wire. I put some printk's in to track it and the problem is
this code in dev.c :
if (skb_queue_len(list)) {
/* avoid overrunning the device queue.. */
if (skb_queue_len(list) > dev->tx_queue_len) {
dev_kfree_skb(skb, FREE_WRITE);
return;
}
}
The dev->buff list grows past the tx_queue_len when my gateway is offline.
It grows even faster when arp is sending. If I arp -d the entry
continously while pinging, the queue will suddenly become empty after
a minute or so - sometimes. Just luck I guess, its quicker to down the
interfaces and re-start them. This started somewhere in the late 1.3
series.
