zero copy transport API

["Ky Srinivasan" <KSRINIVASAN@xxxxxxxxxx>]

I am looking at using the page based API for sending data over TCP/IP. How is 
the client notified that the data has been sent and acknowledged and it is ok 
for the client to potentially reuse the memory. My application is an in-kernel 
application. I had asked this question to Alan and he suggested that I should 
send this question to you.
