* hifn_command_t
*
* This is the control structure used to pass commands to hifn_encrypt().
*
* flags
* -----
* Flags is the bitwise "or" values for command configuration. A single
* 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).
* *** Value ignored if cryptography not used ***
*

* Function: hifn_crypto
*
* Purpose: Called by external drivers to begin an encryption on the
* HIFN board.
*
* Blocking/Non-blocking Issues
* ============================
* The driver cannot block in hifn_crypto (no calls to tsleep) currently.
* hifn_crypto() returns HIFN_CRYPTO_RINGS_FULL if there is not enough
* room in any of the rings for the request to proceed.
*
* Return Values
* =============
* 0 for success, negative values on error
*
* Defines for negative error codes are:
*
* HIFN_CRYPTO_BAD_INPUT : The passed in command had invalid settings.
* HIFN_CRYPTO_RINGS_FULL : All DMA rings were full and non-blocking
* behaviour was requested.
