Thanks for your reply. First thing is that I do not want to modify the existing cifs driver.

I have my own virtual Ethernet driver, where the skb buffer is available to parse. Now,

I want to extract the cifs header from this skb buffer, and based on the cifs header contents

( mainly I am looking for return status), I have to redirect the packet to different destination.

Thanks,

Ramana.

Depending what you are trying to do, it may be best to add your code
to the CIFS driver at the points where the driver is examining the
header fields in question.

What "do some stuff" are you trying to achieve?
