Hello linux-kernel:

I do some work on tcp-zero-copy for kernel 2.6.12-6 ( vanilla ) , Here is the patch . Please review and discussion it .

The patch modify mainly these files below :
(1) include/linux/skbuff.h : add a zccd_t struct , it include the zero-copy's callback function pointer and reference count. (2)include/net/tcp.h : add a new function tcp_sendpage_zccd( ) . It was used as send a memory page to TCP/IP stack. (3)net/core/dev.c (4)net/core/skbuff.c : process the initial ,refcount and release of zccd information. (5)net/ipv4/tcp.c : call the tcp_sendpage_zccd() function to send a memory page.

1) Why, we already have zero-copy?

2) Please send to [email protected], which is where the people who maintain this code live.

	Jeff
