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.
