# Project goal
SK Zero copy project
This project is network packets receive from kernel space or send to userspace by zero copy.
Both are implemented as a single kernel module for Linux.

This project have the same goal with netmap.
you can check the link http://info.iet.unipi.it/~luigi/netmap/ for the project goal.

I want it is more easy to use.

Please check the kernel patch linux-2.6.32-504.3.3.el6-zcopy.patch
I hope kernel upstream will use it as standard interface for packets zero copy.

Here is another project for you want to compile as a module.

# Dir introduce
driver: including zero copy driver and kernel patch.
example: including send forward and recive sample program.
include: using for application head file.
lib:     using for application lib file.

# Test ENV
centOS 6.5 kernel linux-2.6.32-504.3.3.el6 patch it then test passed.
for e1000 driver you needn't change anyting but please reload e1000 drver before test it.

# Usage for reload e1000
rmmod e1000
modprobe e1000 copybreak=0 //disable copybreak
