+/*
+ * 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.
