This is a replacement for #21289
tc.sh is used to limit bandwidth. I ran it and it is limiting my bandwidth. When I ran it, I got one error. I have not found an explanation anywhere of what the error means, but my best guess is consistent with the result, so I propose the explanatory comment to save others time when they use it and also get the error.

yes, i am okay with adding this comment, i am not happy with all the hassle around it though, it makes me reluctant to comment at all if every fixup is going to result in a new PR cycle
i would also ideally prefer putting some more effort in it: prevent that error from happening in the first place, so that no one has to be surprised by it, for example by checking if there are tc rules and not sending the command unnecessarily (i don't use the tool myself so consider this a random bs suggestion)
that said, LGTM ACK 3a0446fad470595db09929695ff02debe12bd4cd
