  46 /*
  47  * The WaveLAN/IEEE adapter is the second generation of the WaveLAN
  48  * from Lucent. Unlike the older cards, the new ones are programmed
  49  * entirely via a firmware-driven controller called the Hermes.
  50  * Unfortunately, Lucent will not release the Hermes programming manual
  51  * without an NDA (if at all). What they do release is an API library
  52  * called the HCF (Hardware Control Functions) which is supposed to
  53  * do the device-specific operations of a device driver for you. The
  54  * publically available version of the HCF library (the 'HCF Light') is
  55  * a) extremely gross, b) lacks certain features, particularly support
  56  * for 802.11 frames, and c) is contaminated by the GNU Public License.
  57  *
  58  * This driver does not use the HCF or HCF Light at all. Instead, it
  59  * programs the Hermes controller directly, using information gleaned
  60  * from the HCF Light code and corresponding documentation.
  61  *
  62  * This driver supports the ISA, PCMCIA and PCI versions of the Lucent
  63  * WaveLan cards (based on the Hermes chipset), as well as the newer
  64  * Prism 2 chipsets with firmware from Intersil and Symbol.
