o If we're using RADIUS and the RADIUS mtu is less than our peers mru/mrru, reduce our mtu to this value for NetBSD too. o Make struct throughput's sample period dynamic and tweak the ppp version number to reflect the extra stuff being passed through the local domain socket as a result (MP mode). o Measure the current throughput based on the number of samples actually taken rather than on the full sample period. o Keep the throughput statisics persistent while being passed to another ppp invocation through the local domain socket. o When showing throughput statistics after the timer has stopped, use the stopped time for overall calculations, not the current time. Also show the stopped time and how long the current throughput has been sampled for. o Use time() consistently in throughput.c o Tighten up the ``show bundle'' output. o Introduce the ``set bandwidth'' command. o Rewrite the ``set autoload'' command. It now takes three arguments and works based on a rolling bundle throughput average compared against the theoretical bundle bandwidth over a given period (read: it's now functional).
