Subject: [PATCH net 0/2] net/sched: sch_qfq: reintroduce lmax bound check for MTU

Reintroduce a bound check for lmax when no attribute is provided and MTU
is used. As the MTU is user controlled, it could be set outside of the
supported bounds for sch_qfq.

Patch 2 introduces tdc test cases to check if these requirements are
still being correctly checked.
