We have seen delays of more than 50ms in class or qdisc dumps, in case
device is under high TX stress.

Add cond_resched() to give a chance to higher prio tasks to get cpu.

Is it OK to sleep (or rather: cond_resched()) in an RCU region?
That's what will potentially happen via tc_dump_qdisc() it seems.
