NAME
       ncp - UltraSPARC T1 server crypto provider device driver

DESCRIPTION
       The  ncp	 device	 driver	 is a multi-threaded, loadable hardware driver
       supporting hardware assisted acceleration of RSA and DSA	 cryptographic
       operations. This support is built into the UltraSPARC T1 processor.

       The  ncp	 driver	 requires  the	presence  of the Solaris Cryptographic
       Framework to enable applications and kernel clients to access the  pro‐
       vided services.

CONFIGURATION
       You  configure  the  ncp	 driver	 by  defining	properties  in	/plat‐
       form/sun4v/kernel/drv/ncp.conf which override the default settings. The
       following property is supported:

       nostats	  Disables the generation of  statistics. The nostats property
		  may be used to help prevent traffic  analysis, but this  may
		  inhibit support personnel.

NETWORK STATISTICS
       Solaris	network	 drivers  must implement statistics variables. The ncp
       driver maintains the following statistics:

       mauXqfull	     Number of times the queue for  MAU	 X  was	 found
			     full when attempting to submit jobs.

       mauXupdate_failure    Number of submit job failures on MAU X.

       mauXsubmit	     Number  of	 jobs  submitted to MAU X since driver
			     load (boot).

       rsapublic	     Total number of  jobs submitted to the device for
			     RSA public key operations.

       rsaprivate	     Total number of  jobs submitted to the device for
			     RSA private key operations.

       dsasign		     Total number of  jobs submitted to the device for
			     DSA signing.

       dsaverify	     Total  number of jobs submitted to the device for
			     DSA verification.

       Additional statistics may be supplied for Sun  support  personnel,  but
       are  not	 useful	 to  Solaris users and are not doc-    umented in this
       manpage.
