I've admittedly been out of action on this for a while, but last time I checked, the IB network stack could be loaded as a kernel module, but a build world was still required to add IB support to userland tools. If this is no longer the case, please excuse my spam. If kernel stability is still a concern, perhaps we could leave the kernel module unloaded by default, but eliminate the need for a build world by enabling IB support by default outside the kernel? I *will* get back to testing this soon, as I'm in the midst of building a new 2,000-core HPC cluster and I have servers available to experiment with. I'm eager to see what kind of performance we can get from a FreeBSD file server with ZFS and FDR IB.
