Network drivers - porting to 2.6 issues

Network drivers - porting to 2.6 issues

[Ram]

Hi,
  I have  ported a wlan driver from 2.4 to 2.6.

  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?.

Regards,
sriram

You forgot to post a link to your source code.
