Why does the kernel crash when the hard_start_xmit routine of the device driver drops the packets for a prolonged time (like sevral minutes)? Is this maybe in bug (im doing this with 2.0.33) or is this related to how the higher protocol handlers deal with this problem. I thought that dropped packets get re-queued in the "do_dev_queue_xmit" routine. The crash occurs when I block the hard_start_xmit routine on purpose by returning 1 immediately. The network traffic is VERY low, i.e. not more then 10 packets get dropped. This behavior seems independent of the device driver that I'm using (its a ISA Wavelan card). Any ideas welcome :-) Thanks, Olaf - To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to [EMAIL PROTECTED]
