I am referring to the porting article in lwn.net. The driver works fine for sometime. after which data transfer becomes very slow. i have telnet to a remote machine. i do ls -Rl / data transfer is ok to start with, then it becomes very slow. also whatever i type on the shell prompt appears after a while. This happens - sometimes it is faster and then slow. this goes on in a cycle. Is there any difference between a 2.4 and 2.6 kernel network stack?. I have changed registeration, changing task queues to work queues and stuff like that. am not sure if the network stack api's and thier meanings have changed. is there anything i should watch out for?. sometimes i do get : NETDEV WATCHDOG: eth1: transmit timed out What does this mean?. is there anything more i should watch out for?.
