NAME
     n2cp - Ultra-SPARC T2 crypto provider device driver

DESCRIPTION
     The  n2cp  device  driver  is  a  multi-threaded,   loadable
     hardware driver supporting hardware-assisted acceleration of
     the following cryptographic operations, which are built into
     the Ultra-SPARC T2 CMT processor:

       DES:    CKM_DES_CBC, CKM_DES_ECB
       DES3:   CKM_DES3_CBC, CKM_DES3_ECB,
       AES:    CKM_AES_CBC, CKM_AES_ECB, CKM_AES_CTR, CKM_AES_CCM, CKM_AES_GCM,
               CKM_AES_GMAC
       RC4:    CKM_RC4
       MD5:    KM_MD5, CKM_MD5_HMAC, CKM_MD5_HMAC_GENERAL,
                   CKM_SSL3_MD5_MAC
       SHA-1:  CKM_SHA_1, CKM_SHA_1_HMAC,
               CKM_SHA_1_HMAC_GENERAL, CKM_SSL3_SHA1_MAC
       SHA-256:CKM_SHA256, CKM_SHA256_HMAC,
               CKM_SHA256_HMAC_GENERAL


CONFIGURATION
     You configure the n2cp driver by defining properties in  the
     /platform/sun4v/kernel/drv/n2cp.conf   which   override  the
     default settings. The following property is supported:

     nostats                     Disables   the   generation   of
                                 statistics.   The  nostats  pro-
                                 perty  may  be  used   to   help
                                 prevent  traffic  analysis, how-
                                 ever, this may  inhibit  support
                                 personnel.


CRYPTO STATISTICS
     Solaris crypto drivers must implement statistics  variables.
     The n2cp driver maintains the following statistics:

     cwqXstate                   State (online,  offline,  error)
                                 of    respective   cryptographic
                                 engine, CWQ X.


     cwqXsubmit                  Number of jobs submitted to  CWQ
                                 X.


     cwqXqfull                   Number of times when  submitting
                                 a  job  that the queue for CWQ X
                                 was full.
