The problem with two modules that are manually inserted here is that netdevsim-related tests expect /sys/bus/netdevsim/new_device to exist (which only exists if netdevsim module has been manually loaded) and specific command format "$TC qdisc add dev $DUMMY handle 1: root teql0" failing since 'telq0', again, only exists when sch_telq is loaded. Overall, I added modprobe here not for theoretical correctness sake but because running tdc.sh on cold system causes error included in the commit message for me. I don't get any other errors related to necessary kernel modules not being loaded for any other kinds of tc tests. >> ./tdc.py -c actions --nobuildebpf >> ./tdc.py -c qdisc
