ISA devices can be 49 * supported either using hard-coded IO port/IRQ settings or via Plug 50 * and Play. The 4500 series devices support 1Mbps and 2Mbps data rates. 51 * The 4800 devices support 1, 2, 5.5 and 11Mbps rates. 52 * 53 * Like the WaveLAN/IEEE cards, the Aironet NICs are all essentially 54 * PCMCIA devices. The ISA and PCI cards are a combination of a PCMCIA 55 * device and a PCMCIA to ISA or PCMCIA to PCI adapter card. There are 56 * a couple of important differences though: 57 * 58 * - Lucent ISA card looks to the host like a PCMCIA controller with 59 * a PCMCIA WaveLAN card inserted. This means that even desktop 60 * machines need to be configured with PCMCIA support in order to 61 * use WaveLAN/IEEE ISA cards. The Aironet cards on the other hand 62 * actually look like normal ISA and PCI devices to the host, so 63 * no PCMCIA controller support is needed 64 * 65 * The latter point results in a small gotcha. The Aironet PCMCIA 66 * cards can be configured for one of two operating modes depending 67 * on how the Vpp1 and Vpp2 programming voltages are set when the 68 * card is activated. In order to put the card in proper PCMCIA 69 * operation (where the CIS table is visible and the interface is 70 * programmed for PCMCIA operation), both Vpp1 and Vpp2 have to be 71 * set to 5 volts. FreeBSD by default doesn't set the Vpp voltages, 72 * which leaves the card in ISA/PCI mode, which prevents it from 73 * being activated as an PCMCIA device. 74 * 75 * Note that some PCMCIA controller software packages for Windows NT 76 * fail to set the voltages as well. 77 * 78 * The Aironet devices can operate in both station mode and access point 79 * mode. Typically, when programmed for station mode, the card can be set 80 * to automatically perform encapsulation/decapsulation of Ethernet II 81 * and 802.3 frames within 802.11 frames so that the host doesn't have 82 * to do it itself. This driver doesn't program the card that way: the 83 * driver handles all of the encapsulation/decapsulation itself. 84 */ 85 86#include "opt_inet.h" 87 88#ifdef INET 89#define ANCACHE /* enable signal strength cache */ 90#endif 91 92#include <sys/param.h> 93#include <sys/ctype.h> 94#include <sys/systm.h> 95#include <sys/sockio.h> 96#include <sys/mbuf.h> 97#include <sys/priv.h> 98#include <sys/proc.h> 99#include <sys/kernel.h> 100#include <sys/socket.h> 101#ifdef ANCACHE 102#include <sys/syslog.h> 103#endif 104#include <sys/sysctl.h> 105 106#include <sys/module.h> 107#include <sys/bus.h> 108#include <machine/bus.h> 109#include <sys/rman.h> 110#include <sys/lock.h> 111#include <sys/mutex.h> 112#include <machine/resource.h> 113#include <sys/malloc.h> 114 115#include <net/if.h> 116#include <net/if_var.h> 117#include <net/if_arp.h> 118#include <net/if_dl.h> 119#include <net/ethernet.h> 120#include <net/if_types.h> 121#include <net/if_media.h> 122 123#include <net80211/ieee80211_var.h> 124#include <net80211/ieee80211_ioctl.h> 125 126#ifdef INET 127#include <netinet/in.h> 128#include <netinet/in_systm.h> 129#include <netinet/in_var.h> 130#include <netinet/ip.h> 131#endif 132 133#include <net/bpf.h> 134 135#include <machine/md_var.h> 136 137#include <dev/an/if_aironet_ieee.h> 138#include <dev/an/if_anreg.h> 139 140/* These are global because we need them in sys/pci/if_an_p.c. */ 141static void an_reset(struct an_softc *);
