Thanks John, Sorry about the so late response.

I could use the if_ntb driver to verify the ntb functions. I could able to
ping between the ntb interfaces. Is there any way, we can measure the
performance of the NTB transactions in FreeBSD. Like we have the ntb_perf
driver in Linux, is there any other generic tool which can be used in
