  143 /*
  144  * The WaveLAN/IEEE cards contain an 802.11 MAC controller which Lucent
  145  * calls 'Hermes.' In typical fashion, getting documentation about this
  146  * controller is about as easy as squeezing blood from a stone. Here
  147  * is more or less what I know:
  148  *
  149  * - The Hermes controller is firmware driven, and the host interacts
  150  *   with the Hermes via a firmware interface, which can change.
  151  *
  152  * - The Hermes is described in a document called: "Hermes Firmware
  153  *   WaveLAN/IEEE Station Functions," document #010245, which of course
  154  *   Lucent will not release without an NDA.
  155  *
  156  * - Lucent has created a library called HCF (Hardware Control Functions)
  157  *   though which it wants developers to interact with the card. The HCF
  158  *   is needlessly complex, ill conceived and badly documented. Actually,
  159  *   the comments in the HCP code itself aren't bad, but the publically
  160  *   available manual that comes with it is awful, probably due largely to
  161  *   the fact that it has been emasculated in order to hide information
  162  *   that Lucent wants to keep proprietary. The purpose of the HCF seems
  163  *   to be to insulate the driver programmer from the Hermes itself so that
  164  *   Lucent has an excuse not to release programming in for it.
  165  *
  166  * - Lucent only makes available documentation and code for 'HCF Light'
  167  *   which is a stripped down version of HCF with certain features not
  168  *   implemented, most notably support for 802.11 frames.
  169  *
  170  * - The HCF code which I have seen blows goats. Whoever decided to
  171  *   use a 132 column format should be shot.
  172  *
  173  * Rather than actually use the Lucent HCF library, I have stripped all
  174  * the useful information from it and used it to create a driver in the
  175  * usual BSD form. Note: I don't want to hear anybody whining about the
  176  * fact that the Lucent code is GPLed and mine isn't. I did not actually
  177  * put any of Lucent's code in this driver: I only used it as a reference
  178  * to obtain information about the underlying hardware. The Hermes
  179  * programming interface is not GPLed, so bite me.
