pe = pending count = number of ack packets I expect.
ua = unacked count = number of ack packets I have to send.

They are rather useless for the administrator.

With protocol B you can see sometimes ua=1 ... This is when the node got
a barrier packet und must wait until all the open write requests are done.

With protocol C you see the number of open write requests in the ua number.
