Current 2.6.22-rc and net-2.6.23 have

        if (band >= q->bands)

Nested netlink attributes, like most qdisc use, instead of
struct tc_rr_qopt (or additionally). The way you've done
it makes it hard to add further attributes later.

BTw, couldn't you just merge sch_rr with prio? AFAICT you
only need a new dequeue function, a new struct Qdisc_ops
and a MODULE_ALIAS.
