+ *  encrypt direction needs to be set:
+ *
+ *	HIFN_ENCODE or HIFN_DECODE
+ *
+ *  To use cryptography, a single crypto algorithm must be included:
+ *
+ *	HIFN_CRYPT_3DES or HIFN_CRYPT_DES
+ *
+ *  To use authentication is used, a single MAC algorithm must be included:
+ *
+ *	HIFN_MAC_MD5 or HIFN_MAC_SHA1
+ *
+ *  By default MD5 uses a 16 byte hash and SHA-1 uses a 20 byte hash.
+ *  If the value below is set, hash values are truncated or assumed
+ *  truncated to 12 bytes:
+ *
+ *	HIFN_MAC_TRUNC
+ *
+ *  Keys for encryption and authentication can be sent as part of a command,
+ *  or the last key value used with a particular session can be retrieved
+ *  and used again if either of these flags are not specified.
+ *
+ *	HIFN_CRYPT_NEW_KEY, HIFN_MAC_NEW_KEY
+ *
+ *  session_num
+ *  -----------
+ *  A number between 0 and 2048 (for DRAM models) or a number between 
+ *  0 and 768 (for SRAM models).  Those who don't want to use session
+ *  numbers should leave value at zero and send a new crypt key and/or
+ *  new MAC key on every command.  If you use session numbers and
+ *  don't send a key with a command, the last key sent for that same
+ *  session number will be used.
+ *
+ *  Warning:  Using session numbers and multiboard at the same time
+ *            is currently broken.
+ *
+ *  mbuf
+ *  ----
+ *  Either fill in the mbuf pointer and npa=0 or
+ *	 fill packp[] and packl[] and set npa to > 0
+ * 
+ *  mac_header_skip
+ *  ---------------
+ *  The number of bytes of the source_buf that are skipped over before
+ *  authentication begins.  This must be a number between 0 and 2^16-1
+ *  and can be used by IPsec implementers to skip over IP headers.
+ *  *** Value ignored if authentication not used ***
+ *
+ *  crypt_header_skip
+ *  -----------------
+ *  The number of bytes of the source_buf that are skipped over before
+ *  the cryptographic operation begins.  This must be a number between 0
+ *  and 2^16-1.  For IPsec, this number will always be 8 bytes larger
+ *  than the auth_header_skip (to skip over the ESP header).

+ *    HIFN_CRYPTO_RINGS_FULL :  All DMA rings were full and non-blocking
