New Revision: 191145
URL: http://svn.freebsd.org/changeset/base/191145

Log:
  	Added a field to the SVCXPRT structure that the nfsv4 server can
  	use to identify if the socket is the same one that a cached request
  	came in on. It is set by nfsrvd_addsock() to a unique value generated
  	by incrementing an unsigned 64bit static variable for each assignment
  	and then the value of xp_sockref is tested to see if it is equal to
  	the value that was saved with the cached reply.
