Add tdc cases locking the codel/fq_codel small-interval uAPI after
the dropping-loop bound (previous patch): sub-tick and two-tick
intervals are ACCEPTED (the loop bound makes them safe), the
1024us boundary is accepted, and a sub-tick target sojourn delay is
accepted (it does not participate in the control law):
codel: 6e44/a8c3/a695/9793 - interval 1us/3us/1024us and
target 1us accepted (rendered 0us/2us/1.02ms/0us by tc)
fq_codel: 1b4d/3540/49c5/3e0f - interval 1us/3us/1024us and
target 1us accepted
The positive cases match the full rendered qdisc line (tc renders
interval 1us as 0us, 3us as 2us, 1024us as 1.02ms), mirroring the
existing tests in these files.
These cases do not test the dropping-loop bound itself: tdc cannot
observe per-dequeue drop counts. c797 (fq_codel target 1 interval 1)
passes unmodified on the patched kernel, which is the uAPI evidence
for the previous patch.
