While experimenting with applying noqueue to a classful queue discipline, we discovered a NULL pointer dereference in the __dev_queue_xmit() path that generates a kernel OOPS:

# dev=enp0s5
# tc qdisc replace dev $dev root handle 1: htb default 1
# tc class add dev $dev parent 1: classid 1:1 htb rate 10mbit
# tc qdisc add dev $dev parent 1:1 handle 10: noqueue
# ping -I $dev -w 1 -c 1 1.1.1.1
