Something is going awry in two existing test:
https://netdev.bots.linux.dev/contest.html?branch=net-next-2024-08-14--15-00&pw-n=0&pass=0
Example:
https://netdev-3.bots.linux.dev/vmksft-net-drv/results/727462/2-queues-py/stdout
I'll take a closer look at the code in the evening, but gotta discard
if from pw already..
