After previous change rshift >= 32 is no longer allowed. Modify the test to use 31, the test doesn't seem to send any traffic so the exact value shouldn't matter.

Add a tdc test case to exercise the just-fixed systematic leak of IDR entries in u32 hnode disposal. Given the IDR in question is confined to the range [1..0x7FF], it is sufficient to create/delete the same filter 2048 times to fill it up and get a nonzero exit status from "tc filter add".

Add 3 tests to check for the expected behaviour of qdisc_tree_reduce_backlog in special scenarios. - The first test checks if the qdisc class is notified of deletion for major handle 'ffff:'. - The second test checks the same as the first test but with 'ffff:' as the root qdisc. - The third test checks if everything works if ingress is active.
