/*
|
|
* 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 the ISA, PCMCIA and PCI versions of the Lucent
|
|
* WaveLan cards (based on the Hermes chipset), as well as the newer
|
|
* Prism 2 chipsets with firmware from Intersil and Symbol.

* Original comments:
|
|
* -----------------
|
|
* wi_cache_store, per rx packet store signal
|
|
* strength in MAC (src) indexed cache.
|
|
*
|
|
* follows linux driver in how signal strength is computed.
|
|
* In ad hoc mode, we use the rx_quality field.
|
|
* signal and noise are trimmed to fit in the range from 47..138.
|
|
* rx_quality field MSB is signal strength.
|
|
* rx_quality field LSB is noise.
|
|
* "quality" is (signal - noise) as is log value.
|
|
* note: quality CAN be negative.
|
|
*
|
|
* In BSS mode, we use the RID for communication quality.
|
|
* TBD: BSS mode is currently untested.
|
|
*
|
|
* Bill's comments:
|
|
* ---------------
|
|
* Actually, we use the rx_quality field all the time for both "ad-hoc"
|
|
* and BSS modes. Why? Because reading an RID is really, really expensive:
|
|
* there's a bunch of PIO operations that have to be done to read a record
|
|
* from the NIC, and reading the comms quality RID each time a packet is
|
|
* received can really hurt performance. We don't have to do this anyway:
|
|
* the comms quality field only reflects the values in the rx_quality field
|
|
* anyway. The comms quality RID is only meaningful in infrastructure mode,
|
|
* but the values it contains are updated based on the rx_quality from
|
|
* frames received from the access point.
|
|
*
|
|
* Also, according to Lucent, the signal strength and noise level values
|
|
* can be converted to dBms by subtracting 149, so I've modified the code
|
|
* to do that instead of the scaling it did originally.
