51  * The WaveLAN/IEEE cards contain an 802.11 MAC controller which Lucent
52  * calls 'Hermes.' In typical fashion, getting documentation about this
53  * controller is about as easy as squeezing blood from a stone. Here
54  * is more or less what I know:
55  *
56  * - The Hermes controller is firmware driven, and the host interacts
57  *   with the Hermes via a firmware interface, which can change.
58  *
59  * - The Hermes is described in a document called: "Hermes Firmware
60  *   WaveLAN/IEEE Station Functions," document #010245, which of course
61  *   Lucent will not release without an NDA.
62  *
63  * - Lucent has created a library called HCF (Hardware Control Functions)
64  *   though which it wants developers to interact with the card. The HCF
65  *   is needlessly complex, ill conceived and badly documented. Actually,
66  *   the comments in the HCP code itself aren't bad, but the publically
67  *   available manual that comes with it is awful, probably due largely to
68  *   the fact that it has been emasculated in order to hide information
69  *   that Lucent wants to keep proprietary. The purpose of the HCF seems
70  *   to be to insulate the driver programmer from the Hermes itself so that
71  *   Lucent has an excuse not to release programming in for it.
72  *
73  * - Lucent only makes available documentation and code for 'HCF Light'
74  *   which is a stripped down version of HCF with certain features not
75  *   implemented, most notably support for 802.11 frames.
76  *
77  * - The HCF code which I have seen blows goats. Whoever decided to
78  *   use a 132 column format should be shot.
79  *
80  * Rather than actually use the Lucent HCF library, I have stripped all
81  * the useful information from it and used it to create a driver in the
82  * usual BSD form. Note: I don't want to hear anybody whining about the
83  * fact that the Lucent code is GPLed and mine isn't. I did not actually
84  * put any of Lucent's code in this driver: I only used it as a reference
85  * to obtain information about the underlying hardware. The Hermes
86  * programming interface is not GPLed, so bite me.
