Socket receive, send

Hey Is there a good documentation on how messages are taking the tour from User calling read/write on socket fd, to kernel handling the actual send/receive functions? I wish to write code to capture the messages (no netfilter - I wish to bypass it) for processing. I know there is a socket->ops structure with functions pointers. I am at the point to look the inet version on that pointers. But if there is a documentation on this it will save me some time. Grzegorz.
