37 * Lucent WaveLAN/IEEE 802.11 PCMCIA driver for FreeBSD.
39 * Written by Bill Paul <wpaul@ctr.columbia.edu>
40 * Electrical Engineering Department
41 * Columbia University, New York City
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.
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.
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.

2613 * wi_cache_store, per rx packet store signal
2614 * strength in MAC (src) indexed cache.
2616 * follows linux driver in how signal strength is computed.
2617 * In ad hoc mode, we use the rx_quality field.
2618 * signal and noise are trimmed to fit in the range from 47..138.
2619 * rx_quality field MSB is signal strength.
2620 * rx_quality field LSB is noise.
2621 * "quality" is (signal - noise) as is log value.
2622 * note: quality CAN be negative.
2624 * In BSS mode, we use the RID for communication quality.
2625 * TBD: BSS mode is currently untested.
2629 * Actually, we use the rx_quality field all the time for both "ad-hoc"
2630 * and BSS modes. Why? Because reading an RID is really, really expensive:
2631 * there's a bunch of PIO operations that have to be done to read a record
2632 * from the NIC, and reading the comms quality RID each time a packet is
2633 * received can really hurt performance. We don't have to do this anyway:
2634 * the comms quality field only reflects the values in the rx_quality field
2635 * anyway. The comms quality RID is only meaningful in infrastructure mode,
2636 * but the values it contains are updated based on the rx_quality from
2637 * frames received from the access point.
2639 * Also, according to Lucent, the signal strength and noise level values
2640 * can be converted to dBms by subtracting 149, so I've modified the code
2641 * to do that instead of the scaling it did originally.
