ing other configuration information using the standard mechanism for optional data.

A Linux IP-over-IB client was able to send DHCDISCOVER, and our FreeBSD server was able to set up BPF and receive it. But when the server tried to send an ARP to make sure that the address it wanted to DHCPOFFER was available, nothing went over the wire. It turns out that if_infiniband interfaces don't transmit link-layer broadcasts.

My colleague Nick was able to solve this, and the rest of the bring-up went smoothly. The fix passes muster internally, but we were hoping to get some more eyes on it before committing it to the main repo.

If anyone wants to take a look: https://github.com/freebsd/freebsd-src/pull/1591

If I don't hear any objections by the end of the week, I'll go ahead and submit it.
