188 * The WaveLAN/IEEE cards contain an 802.11 MAC controller which Lucent
189 * calls 'Hermes.' In typical fashion, getting documentation about this
190 * controller is about as easy as squeezing blood from a stone. Here
191 * is more or less what I know:
192 *
193 * - The Hermes controller is firmware driven, and the host interacts
194 * with the Hermes via a firmware interface, which can change.
195 *
196 * - The Hermes is described in a document called: "Hermes Firmware
197 * WaveLAN/IEEE Station Functions," document #010245, which of course
198 * Lucent will not release without an NDA.
199 *
200 * - Lucent has created a library called HCF (Hardware Control Functions)
201 * though which it wants developers to interact with the card. The HCF
202 * is needlessly complex, ill conceived and badly documented. Actually,
203 * the comments in the HCP code itself aren't bad, but the publically
204 * available manual that comes with it is awful, probably due largely to
205 * the fact that it has been emasculated in order to hide information
206 * that Lucent wants to keep proprietary. The purpose of the HCF seems
207 * to be to insulate the driver programmer from the Hermes itself so that
208 * Lucent has an excuse not to release programming in for it.
209 *
210 * - Lucent only makes available documentation and code for 'HCF Light'
211 * which is a stripped down version of HCF with certain features not
212 * implemented, most notably support for 802.11 frames.
213 *
214 * - The HCF code which I have seen blows goats. Whoever decided to
215 * use a 132 column format should be shot.
216 *
217 * Rather than actually use the Lucent HCF library, I have stripped all
218 * the useful information from it and used it to create a driver in the
219 * usual BSD form. Note: I don't want to hear anybody whining about the
220 * fact that the Lucent code is GPLed and mine isn't. I did not actually
221 * put any of Lucent's code in this driver: I only used it as a reference
222 * to obtain information about the underlying hardware. The Hermes
223 * programming interface is not GPLed, so bite me.
