  44 /*
  45  * The WaveLAN/IEEE adapter is the second generation of the WaveLAN
  46  * from Lucent. Unlike the older cards, the new ones are programmed
  47  * entirely via a firmware-driven controller called the Hermes.
  48  * Unfortunately, Lucent will not release the Hermes programming manual
  49  * without an NDA (if at all). What they do release is an API library
  50  * called the HCF (Hardware Control Functions) which is supposed to
  51  * do the device-specific operations of a device driver for you. The
  52  * publically available version of the HCF library (the 'HCF Light') is
  53  * a) extremely gross, b) lacks certain features, particularly support
  54  * for 802.11 frames, and c) is contaminated by the GNU Public License.
  55  *
  56  * This driver does not use the HCF or HCF Light at all. Instead, it
  57  * programs the Hermes controller directly, using information gleaned
  58  * from the HCF Light code and corresponding documentation.
  59  *
  60  * This driver supports the ISA, PCMCIA and PCI versions of the Lucent
  61  * WaveLan cards (based on the Hermes chipset), as well as the newer
  62  * Prism 2 chipsets with firmware from Intersil and Symbol.

2612  *
2613  * follows linux driver in how signal strength is computed.
2614  * In ad hoc mode, we use the rx_quality field.
2615  * signal and noise are trimmed to fit in the range from 47..138.
2616  * rx_quality field MSB is signal strength.
2617  * rx_quality field LSB is noise.
2618  * "quality" is (signal - noise) as is log value.
2619  * note: quality CAN be negative.
2620  *
2621  * In BSS mode, we use the RID for communication quality.
2622  * TBD:  BSS mode is currently untested.
2623  *
2624  * Bill's comments:
2625  * ---------------
2626  * Actually, we use the rx_quality field all the time for both "ad-hoc"
2627  * and BSS modes. Why? Because reading an RID is really, really expensive:
2628  * there's a bunch of PIO operations that have to be done to read a record
2629  * from the NIC, and reading the comms quality RID each time a packet is
2630  * received can really hurt performance. We don't have to do this anyway:
2631  * the comms quality field only reflects the values in the rx_quality field
2632  * anyway. The comms quality RID is only meaningful in infrastructure mode,
2633  * but the values it contains are updated based on the rx_quality from
2634  * frames received from the access point.
2635  *
2636  * Also, according to Lucent, the signal strength and noise level values
2637  * can be converted to dBms by subtracting 149, so I've modified the code
2638  * to do that instead of the scaling it did originally.
