ISA devices can be 47 * supported either using hard-coded IO port/IRQ settings or via Plug 48 * and Play. The 4500 series devices support 1Mbps and 2Mbps data rates. 49 * The 4800 devices support 1, 2, 5.5 and 11Mbps rates. 50 * 51 * Like the WaveLAN/IEEE cards, the Aironet NICs are all essentially 52 * PCMCIA devices. The ISA and PCI cards are a combination of a PCMCIA 53 * device and a PCMCIA to ISA or PCMCIA to PCI adapter card. There are 54 * a couple of important differences though: 55 * 56 * - Lucent ISA card looks to the host like a PCMCIA controller with 57 * a PCMCIA WaveLAN card inserted. This means that even desktop 58 * machines need to be configured with PCMCIA support in order to 59 * use WaveLAN/IEEE ISA cards. The Aironet cards on the other hand 60 * actually look like normal ISA and PCI devices to the host, so 61 * no PCMCIA controller support is needed 62 * 63 * The latter point results in a small gotcha. The Aironet PCMCIA 64 * cards can be configured for one of two operating modes depending 65 * on how the Vpp1 and Vpp2 programming voltages are set when the 66 * card is activated. In order to put the card in proper PCMCIA 67 * operation (where the CIS table is visible and the interface is 68 * programmed for PCMCIA operation), both Vpp1 and Vpp2 have to be 69 * set to 5 volts. FreeBSD by default doesn't set the Vpp voltages, 70 * which leaves the card in ISA/PCI mode, which prevents it from 71 * being activated as an PCMCIA device. 72 * 73 * Note that some PCMCIA controller software packages for Windows NT 74 * fail to set the voltages as well. 75 * 76 * The Aironet devices can operate in both station mode and access point 77 * mode. Typically, when programmed for station mode, the card can be set 78 * to automatically perform encapsulation/decapsulation of Ethernet II 79 * and 802.3 frames within 802.11 frames so that the host doesn't have 80 * to do it itself. This driver doesn't program the card that way: the 81 * driver handles all of the encapsulation/decapsulation itself. 82 */ 83 84 #include "opt_inet.h" 85 86 #ifdef INET 87 #define ANCACHE /* enable signal strength cache */ 88 #endif 89 90 #include <sys/param.h> 91 #include <sys/ctype.h> 92 #include <sys/systm.h> 93 #include <sys/sockio.h> 94 #include <sys/mbuf.h> 95 #include <sys/priv.h> 96 #include <sys/proc.h> 97 #include <sys/kernel.h> 98 #include <sys/socket.h> 99 #ifdef ANCACHE 100 #include <sys/syslog.h> 101 #endif 102 #include <sys/sysctl.h> 103 104 #include <sys/module.h> 105 #include <sys/sysctl.h> 106 #include <sys/bus.h> 107 #include <machine/bus.h> 108 #include <sys/rman.h> 109 #include <sys/lock.h> 110 #include <sys/mutex.h> 111 #include <machine/resource.h> 112 #include <sys/malloc.h> 113 114 #include <net/if.h> 115 #include <net/if_arp.h> 116 #include <net/if_dl.h> 117 #include <net/ethernet.h> 118 #include <net/if_types.h> 119 #include <net/if_media.h> 120 121 #include <net80211/ieee80211_var.h> 122 #include <net80211/ieee80211_ioctl.h> 123 124 #ifdef INET 125 #include <netinet/in.h> 126 #include <netinet/in_systm.h> 127 #include <netinet/in_var.h> 128 #include <netinet/ip.h> 129 #endif 130 131 #include <net/bpf.h> 132 133 #include <machine/md_var.h> 134 135 #include <dev/an/if_aironet_ieee.h> 136 #include <dev/an/if_anreg.h> 137 138 /* These are global because we need them in sys/pci/if_an_p.c. */ 139 static void an_reset(struct an_softc *);
