Sascha Wildner has ported FreeBSD’s driver, for LSI Fusion-MPT 3/3.5 SAS controllers. It includes mpr(4), mps(4), and the mpsutil(8)/mprutil(8) management program. It’s in the kernel by default, in fact.
A running description of activity related to DragonFly BSD.
That commit did not include the mps(4) driver, just mpr(4) and mp{r,s}util(4) (same tool for both drivers).
