In addition to what Jason wrote: personally I use the distro-provided IB kernel drivers and user space with Linux distributions that track the mainline kernel closely and either the distro-provided IB software or OFED on enterprise Linux distributions. While using OFED has the advantage of having the latest IB features available, a disadvantage is that the entire OFED software stack has to be recompiled after each kernel update. And most Linux distributors frequently release updated kernels, e.g. because of security fixes.
