I think it's fine that your low-level driver can work without ib_core,
ib_mad and the rest loaded. But I still (after all this discussion)
don't understand why you need to have two SMA implementations to
handle this along with the code to switch between the two modes like:
> + list_for_each_entry(dd, &ipath_dev_list, ipath_list) {
> + if (!(dd->ipath_flags & IPATH_INITTED))
> + continue;
> + *dd->ipath_statusp &= ~IPATH_STATUS_SMA;
> + if (ipath_verbs_registered)
> + *dd->ipath_statusp |= IPATH_STATUS_OIB_SMA;
> + }
You also have all the functions like recv_subn_get_nodeinfo() etc. for
handling SM queries. Presumably all this is duplicated in the
userspace SMA. Why can't you get down to one NodeInfo query handler?
