We are sending data to controller at wrong average rate not equal to
1 packet / SDU interval, if Transport_Latency is not an integer multiple
of SDU_Interval. The calculation currently may also give zero, so no
data gets sent.
We are sending data in bursts of num ~= Transport_Latency/SDU_Interval
packets, in hopes that possibly larger timer interval makes things more
efficient.
Fix the data rate by sending num packets every num*SDU_Interval, so that
the average data rate is correct.
Also fix use of itimerspect.it_value with TFD_TIMER_ABSTIME. The value
set previously is going to always be in the past in CLOCK_MONOTONIC so
just set it to 1.
