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