I apologize for not yet reviewing all the code. I take that last bit to mean the drivers can reach up into sockets given those functions? I gather this is due to the work necessary to implement RDMA over TCP? > The current state of the code can be seen at: > http://157.22.130.171/svn/branches/projects/iwarp/sys/ Is there a simple way to get just that directory without doing a svn on your whole repo? And if not, what's the easiest way to just grab that stuff?
