2) If I set latency = 50ms and a jitter = 300ms, tabledist can give me
a negative number. This value is addes to cb->time_to_send, so it
could change it to a negative value. Should we only accept positives
number before add it to cb->time_to_send? or will
q->qdisc->enqueue(skb, q->qdisc) put the package on the queue in a
special way so it will be handled "before" other packages alrealy on
the queue but with gretaer time_to_send?

probably should bound the value to 0 before the addition, to avoid large
wraparound problems, but since enqueue checks for for time it will work
as long as delta less than 2^32/2.

I think the value should be restricted to be positive and greater than
zero. Becuase if a negative number is allowed we will be "losing"
packages to be reordered, hence we will not be reordering, say 25%, of
packages instead we will be reordering about 15%.
In other words, packages that should be reordered will not be
reordered because its new time to send will be the same as the old
time to send.
