50 The tail pointer tails or trails the hardware pointer. When the
51 hardware is ahead, the tail pointer will be pointing at a "full"
53 and advance the tail pointer.  Thus, when there is flowing RX traffic,
54 all of the descrs in front of the tail pointer should be "full", and
56 flowing, then the tail pointer can catch up to the hardware pointer.
60 The head pointer (somewhat mis-named) follows after the tail pointer.

68 RX traffic is flowing, then the head pointer can catch up to the tail
69 pointer, at which point the OS will notice that the head descr is
78 of the ring, starting at the tail pointer, and listing the status
117 pointer will catch up to the head, notice the not-empty condition,
