Tested packet-bricks for FreeBSD.
--- It passes basic tests. It is now ready for external testing!
--- kqueue() did not work with netmap setup. May email Luigi about this
--- Reverted to poll() framework to sniff for incoming packets (for FreeBSD) :(
------ May revert the Linux version to poll() as well in order to create a common abstraction layer
