| 46 | /* |
| 47 | * The Aironet 4500/4800 series cards come in PCMCIA, ISA and PCI form. |
| 48 | * This driver supports all three device types (PCI devices are supported |
| 49 | * through an extra PCI shim: /sys/dev/an/if_an_pci.c). ISA devices can be |
| 50 | * supported either using hard-coded IO port/IRQ settings or via Plug |
| 51 | * and Play. The 4500 series devices support 1Mbps and 2Mbps data rates. |
| 52 | * The 4800 devices support 1, 2, 5.5 and 11Mbps rates. |
| 53 | * |
| 54 | * Like the WaveLAN/IEEE cards, the Aironet NICs are all essentially |
| 55 | * PCMCIA devices. The ISA and PCI cards are a combination of a PCMCIA |
| 56 | * device and a PCMCIA to ISA or PCMCIA to PCI adapter card. There are |
| 57 | * a couple of important differences though: |
| 58 | * |
| 59 | * - Lucent ISA card looks to the host like a PCMCIA controller with |
| 60 | * a PCMCIA WaveLAN card inserted. This means that even desktop |
| 61 | * machines need to be configured with PCMCIA support in order to |
| 62 | * use WaveLAN/IEEE ISA cards. The Aironet cards on the other hand |
| 63 | * actually look like normal ISA and PCI devices to the host, so |
| 64 | * no PCMCIA controller support is needed |
| 65 | * |
| 66 | * The latter point results in a small gotcha. The Aironet PCMCIA |
| 67 | * cards can be configured for one of two operating modes depending |
| 68 | * on how the Vpp1 and Vpp2 programming voltages are set when the |
| 69 | * card is activated. In order to put the card in proper PCMCIA |
| 70 | * operation (where the CIS table is visible and the interface is |
| 71 | * programmed for PCMCIA operation), both Vpp1 and Vpp2 have to be |
| 72 | * set to 5 volts. FreeBSD by default doesn't set the Vpp voltages, |
| 73 | * which leaves the card in ISA/PCI mode, which prevents it from |
| 74 | * being activated as an PCMCIA device. |
| 75 | * |
| 76 | * Note that some PCMCIA controller software packages for Windows NT |
| 77 | * fail to set the voltages as well. |
| 78 | * |
| 79 | * The Aironet devices can operate in both station mode and access point |
| 80 | * mode. Typically, when programmed for station mode, the card can be set |
| 81 | * to automatically perform encapsulation/decapsulation of Ethernet II |
| 82 | * and 802.3 frames within 802.11 frames so that the host doesn't have |
| 83 | * to do it itself. This driver doesn't program the card that way: the |
| 84 | * driver handles all of the encapsulation/decapsulation itself. |
