Can I access NIC directly from user space?
 
Hi,
I want to write one application by which I can directly access NIC driver (read/write to it)

Can anyone help me out ...?

Are you saying you want to edit the driver, as in the file that plugs into the kernel, or you want to interface directly with the NIC? If you mean directly interface, how directly? Do you want to be able to send individual packets, or are you looking to rewrite tcp/ip?

You need to be in ring0 to talk to a device, so no.
