* Applied the last patch in Bug 2306, which changes the portals router/NAL

   forwarding interface from a single struct iovec for the message header +
   payload, to passing the message header by pointer, and the message body
   by ptl_kiov_t (== page,offset,size).  This restores portals router
   performance by allowing it to use socknal zero copy again.

*  Applied the socknal connection load balancing fix from Bug 2817
