|
|
* The WaveLAN/IEEE adapter is the second generation of the WaveLAN
|
|
* from Lucent. Unlike the older cards, the new ones are programmed
|
|
* entirely via a firmware-driven controller called the Hermes.
|
|
* Unfortunately, Lucent will not release the Hermes programming manual
|
|
* without an NDA (if at all). What they do release is an API library
|
|
* called the HCF (Hardware Control Functions) which is supposed to
|
|
* do the device-specific operations of a device driver for you. The
|
|
* publically available version of the HCF library (the 'HCF Light') is
|
|
* a) extremely gross, b) lacks certain features, particularly support
|
|
* for 802.11 frames, and c) is contaminated by the GNU Public License.
|
|
*
|
|
* This driver does not use the HCF or HCF Light at all. Instead, it
|
|
* programs the Hermes controller directly, using information gleaned
|
|
* from the HCF Light code and corresponding documentation.
|
|
*
|
|
* This driver supports both the PCMCIA and ISA versions of the
|
|
* WaveLAN/IEEE cards. Note however that the ISA card isn't really
|
|
* anything of the sort: it's actually a PCMCIA bridge adapter
|
|
* that fits into an ISA slot, into which a PCMCIA WaveLAN card is
|
|
* inserted. Consequently, you need to use the pccard support for
|
|
* both the ISA and PCMCIA adapters.
