i've added some trivial functions.

you can use the following fragments to implement your ioctls.

"get" ioctl:
        strategyname = bufq_getstrategyname(sc->sc_bufq);

"set" ioctl:
        error = bufq_alloc(&new, strategyname, BUFQ_EXACT);
        if (error) {
                goto out;
        }
        s = splbio();   /* driver dependent */
        old = sc->sc_bufq;
        sc->sc_bufq = new;
        bufq_move(new, old);
        splx(s);        /* driver dependent */
        bufq_free(old);
