Then I would suggest sending the patch for review and inclusion in the kernel. Documentation/SubmittingPatches and Documentation/SubmittingDrivers in the kernel source tree may be helpful. However I would still probably think that IPoIB for non-IB networks is unnecessary complexity -- the mismatch of IB and traditional ethernet/IP semantics makes even IPoIB a bit of a problem for some apps, and then layering a not-IB network on top of that is probably not a good idea. - R. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
