Doesn't mean they are in the correct place either, but perhaps it's too

See, on the kernel side these are called "LINUX_MIB*" which seems
perfectly sane and I wouldn't even think the statistic is out of
place.  On the user-mode side these are all reported in
/proc/net/netstat as TcpExt statistics.  I can tell you that I don't
look at TCP statistics when I'm debugging/testing UDP issues
(apparently I should).
