trivia:
If you redo these, it'd be nicer not to use " " after each
fixed string, but use " " before each fixed string.
The final output string would be 1 byte shorter overall and
not have an excess " " before the newline.
The declaration of i doesn't need initialization to 0:
i = snprintf(buf, INFO_STRING_LEN, "Features: PF-id[%d]", ...
would work.
