| 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. |

| 2613 | * ----------------- |
| 2614 | * wi_cache_store, per rx packet store signal |
| 2615 | * strength in MAC (src) indexed cache. |
| 2616 | * |
| 2617 | * follows linux driver in how signal strength is computed. |
| 2618 | * In ad hoc mode, we use the rx_quality field. |
| 2619 | * signal and noise are trimmed to fit in the range from 47..138. |
| 2620 | * rx_quality field MSB is signal strength. |
| 2621 | * rx_quality field LSB is noise. |
| 2622 | * "quality" is (signal - noise) as is log value. |
| 2623 | * note: quality CAN be negative. |
| 2624 | * |
| 2625 | * In BSS mode, we use the RID for communication quality. |
| 2626 | * TBD: BSS mode is currently untested. |
| 2627 | * |
| 2628 | * Bill's comments: |
| 2629 | * --------------- |
| 2630 | * Actually, we use the rx_quality field all the time for both "ad-hoc" |
| 2631 | * and BSS modes. Why? Because reading an RID is really, really expensive: |
| 2632 | * there's a bunch of PIO operations that have to be done to read a record |
| 2633 | * from the NIC, and reading the comms quality RID each time a packet is |
| 2634 | * received can really hurt performance. We don't have to do this anyway: |
| 2635 | * the comms quality field only reflects the values in the rx_quality field |
| 2636 | * anyway. The comms quality RID is only meaningful in infrastructure mode, |
| 2637 | * but the values it contains are updated based on the rx_quality from |
| 2638 | * frames received from the access point. |
| 2639 | * |
| 2640 | * Also, according to Lucent, the signal strength and noise level values |
| 2641 | * can be converted to dBms by subtracting 149, so I've modified the code |
| 2642 | * to do that instead of the scaling it did originally. |
