Hi Rui,
There are no existing applications, but these two calls are for
developing new application on 10G links.
Currently I use netgraph, especially ng_socket node. And a simple
recvfrom() on a ng_socket costs ~5us or so (200K per second). And
there are many netgraph sockets. So it's good to reduce the time by
ultilizing send/recvmmsg() if there are these two syscalls. Even a
simple-loop like implmentation like linux's will be good as Luigi
has suggested.
As the writer of netgraph I would like to point out that it was never
designed to be a high throughput service.
I'm happy thought that it CAN be used at these speeds but I designed
it for prototyping and for serial line speeds.
The idea was that once something was prototyped out, one would take
the code from all the modules used and create
a special purpose module that dd what you need.
The fact that people have not needed the last step is gratifying but
surprising.

NetBSD 7.0 has just introduced these two syscalls.
And Linux also has them.
Does FreeBSD have them? Or plan to support them in the future?
FreeBSD does not have them. It doesn't seem especially hard to
implement, though. Do you know any major application already using
them?
