The times for close_delay and closing_wait are in hundredths of a second, not milliseconds. Fix the documentation instead of trying to use millisecond values (which would have to be rounded). Signed-off-by: Simon Arlott <simon@xxxxxxxxxxx> --- If you'd prefer, I can fold the second part of this into my previous patch which shouldn't have documented it as milliseconds in the first place (but I copied it from the other entry).
