Subject: Update netstat(1) for recent conversion of netipx to queue(9) from
 home-brew linked lists.  Read in the ipxpcb_list structure first in order to
 find the first pcb pointer.  Then follow the chain as before, only the
 termination condition is a NULL next pointer rather than a next pointer equal
 to the original offset.
