[j-nsp] MX80 / 3D MIC buffers/queues

[Nikita Shirokov]

this output shows you how many queues have been consumed (and maximum
ammount of queues). actual packet's buffering happened on the mqchip. i
dont remebemer the command which shows you how many of packet's buffer have
been consumed. will try to find it.
