  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.

2618  * strength in MAC (src) indexed cache.
2619  *
2620  * follows linux driver in how signal strength is computed.
2621  * In ad hoc mode, we use the rx_quality field.
2622  * signal and noise are trimmed to fit in the range from 47..138.
2623  * rx_quality field MSB is signal strength.
2624  * rx_quality field LSB is noise.
2625  * "quality" is (signal - noise) as is log value.
2626  * note: quality CAN be negative.
2627  *
2628  * In BSS mode, we use the RID for communication quality.
2629  * TBD:  BSS mode is currently untested.
2630  *
2631  * Bill's comments:
2632  * ---------------
2633  * Actually, we use the rx_quality field all the time for both "ad-hoc"
2634  * and BSS modes. Why? Because reading an RID is really, really expensive:
2635  * there's a bunch of PIO operations that have to be done to read a record
2636  * from the NIC, and reading the comms quality RID each time a packet is
2637  * received can really hurt performance. We don't have to do this anyway:
2638  * the comms quality field only reflects the values in the rx_quality field
2639  * anyway. The comms quality RID is only meaningful in infrastructure mode,
2640  * but the values it contains are updated based on the rx_quality from
2641  * frames received from the access point.
2642  *
2643  * Also, according to Lucent, the signal strength and noise level values
2644  * can be converted to dBms by subtracting 149, so I've modified the code
2645  * to do that instead of the scaling it did originally.
