    113  * The WaveLAN/IEEE cards contain an 802.11 MAC controller which Lucent
    114  * calls 'Hermes.' In typical fashion, getting documentation about this
    115  * controller is about as easy as squeezing blood from a stone. Here
    116  * is more or less what I know:
    117  *
    118  * - The Hermes controller is firmware driven, and the host interacts
    119  *   with the Hermes via a firmware interface, which can change.
    120  *
    121  * - The Hermes is described in a document called: "Hermes Firmware
    122  *   WaveLAN/IEEE Station Functions," document #010245, which of course
    123  *   Lucent will not release without an NDA.
    124  *
    125  * - Lucent has created a library called HCF (Hardware Control Functions)
    126  *   though which it wants developers to interact with the card. The HCF
    127  *   is needlessly complex, ill conceived and badly documented. Actually,
    128  *   the comments in the HCP code itself aren't bad, but the publically
    129  *   available manual that comes with it is awful, probably due largely to
    130  *   the fact that it has been emasculated in order to hide information
    131  *   that Lucent wants to keep proprietary. The purpose of the HCF seems
    132  *   to be to insulate the driver programmer from the Hermes itself so that
    133  *   Lucent has an excuse not to release programming in for it.
    134  *
    135  * - Lucent only makes available documentation and code for 'HCF Light'
    136  *   which is a stripped down version of HCF with certain features not
    137  *   implemented, most notably support for 802.11 frames.
    138  *
    139  * - The HCF code which I have seen blows goats. Whoever decided to
    140  *   use a 132 column format should be shot.
    141  *
    142  * Rather than actually use the Lucent HCF library, I have stripped all
    143  * the useful information from it and used it to create a driver in the
    144  * usual BSD form. Note: I don't want to hear anybody whining about the
    145  * fact that the Lucent code is GPLed and mine isn't. I did not actually
    146  * put any of Lucent's code in this driver: I only used it as a reference
    147  * to obtain information about the underlying hardware. The Hermes
    148  * programming interface is not GPLed, so bite me.
