Fri 24 Apr 2015 07:36:54 PM UTC, comment #1: I'm afraid the code won't work. The reason is that you removed memory copies (using netbuf_ref, not copying the data into the netbuf).

I've developed a sendmsg() addition to the sockets API. It follows the Open Group specification to provide support for scatter/gather IO from applications.
