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.
