/*
|
|
* 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.
