- * Select PLL configuration for 795x parts. This is complicated in

- * The reference clock is derived from an external clock through a
- * multiplier. The external clock is either the host bus (i.e. PCI)
- * or an external clock generator. When using the PCI bus we assume
- * the clock is either 33 or 66 MHz; for an external source we cannot
- * tell the speed.
- *
- * PLL configuration is done with a string: "pci" for PCI bus, or "ext"
- * for an external source, followed by the frequency. We calculate
- * the appropriate multiplier and PLL register contents accordingly.
- * When no configuration is given we default to "pci66" since that
- * always will allow the card to work. If a card is using the PCI
- * bus clock and in a 33MHz slot then it will be operating at half
- * speed until the correct information is provided.
- *
- * We use a default setting of "ext66" because according to Mike Ham
- * of HiFn, almost every board in existence has an external crystal
- * populated at 66Mhz. Using PCI can be a problem on modern motherboards,
- * because PCI33 can have clocks from 0 to 33Mhz, and some have
- * non-PCI-compliant spread-spectrum clocks, which can confuse the pll.

- * 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 ***

- * The driver cannot block in hifn_crypto (no calls to tsleep) currently.

- *
- * 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
