--- Comment #3 from Vincenzo Maffione <vmaffione@FreeBSD.org> ---
Created attachment 201394
  --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D201394&action=
=3Dedit
Example netmap program using kqueue to read or write from a netmap port.

As far as I can see, now kqueue/kevent works correctly, and syncs the tail =
of
the TX ring.
See for instance the program in attachment. I tried that on VALE and pipe
ports.
