Added output of rk and pw
Update experiment parameters

Neither IP nor XIA can handle update rates above 10^5, so no tests
should be performed above that rate.

The update rate experiment is reworked to change with the destination
address as well.

64B packets cannot hold any destination addresses bigger than fb0 in
XIA, so no need to add those tests. Similarly, 128B packets cannot
hold the fb3 XIA destination address.
