Unlike the older cards, the new ones are programmed 46 * entirely via a firmware-driven controller called the Hermes. 47 * Unfortunately, Lucent will not release the Hermes programming manual 48 * without an NDA (if at all). What they do release is an API library 49 * called the HCF (Hardware Control Functions) which is supposed to 50 * do the device-specific operations of a device driver for you. The 51 * publically available version of the HCF library (the 'HCF Light') is 52 * a) extremely gross, b) lacks certain features, particularly support 53 * for 802.11 frames, and c) is contaminated by the GNU Public License. 54 * 55 * This driver does not use the HCF or HCF Light at all. Instead, it 56 * programs the Hermes controller directly, using information gleaned 57 * from the HCF Light code and corresponding documentation. 58 * 59 * This driver supports both the PCMCIA and ISA versions of the 60 * WaveLAN/IEEE cards. Note however that the ISA card isn't really 61 * anything of the sort: it's actually a PCMCIA bridge adapter 62 * that fits into an ISA slot, into which a PCMCIA WaveLAN card is 63 * inserted. Consequently, you need to use the pccard support for 64 * both the ISA and PCMCIA adapters. 65 */ 66 67 /* 68 * FreeBSD driver ported to NetBSD by Bill Sommerfeld in the back of the 69 * Oslo IETF plenary meeting. 70 */ 71 72 #include <sys/cdefs.h> 73 __KERNEL_RCSID(0, "$NetBSD: wi.c,v 1.40 2002/02/17 19:24:18 martin Exp $"); 74 75 #define WI_HERMES_AUTOINC_WAR /* Work around data write autoinc bug. */ 76 #define WI_HERMES_STATS_WAR /* Work around stats counter bug. */ 77 78 #include "bpfilter.h" 79 80 #include <sys/param.h> 81 #include <sys/systm.h> 82 #include <sys/callout.h> 83 #include <sys/device.h> 84 #include <sys/socket.h> 85 #include <sys/mbuf.h> 86 #include <sys/ioctl.h> 87 #include <sys/kernel.h> /* for hz */ 88 #include <sys/proc.h> 89 90 #include <net/if.h> 91 #include <net/if_dl.h> 92 #include <net/if_media.h> 93 #include <net/if_ether.h> 94 #include <net/if_ieee80211.h> 95 96 #if NBPFILTER > 0 97 #include <net/bpf.h> 98 #include <net/bpfdesc.h> 99 #endif 100 101 #include <machine/bus.h> 102 103 #include <dev/ic/wi_ieee.h> 104 #include <dev/ic/wireg.h> 105 #include <dev/ic/wivar.h> 106 107 static void wi_reset __P((struct wi_softc *)); 108 static int wi_ioctl __P((struct ifnet *, u_long, caddr_t)); 109 static void wi_start __P((struct ifnet *)); 110 static void wi_watchdog __P((struct ifnet *)); 111 static int wi_init __P((struct ifnet *)); 112 static void wi_stop __P((struct ifnet *, int)); 113 static void wi_rxeof __P((struct wi_softc *)); 114 static void wi_txeof __P((struct wi_softc *, int)); 115 static void wi_update_stats __P((struct wi_softc *)); 116 static void wi_setmulti __P((struct wi_softc *)); 117 118 static int wi_cmd __P((struct wi_softc *, int, int)); 119 static int wi_read_record __P((struct wi_softc *, struct wi_ltv_gen *)); 120 static int wi_write_record __P((struct wi_softc *, struct wi_ltv_gen *)); 121 static int wi_read_data __P((struct wi_softc *, int, 122 int, caddr_t, int)); 123 static int wi_write_data __P((struct wi_softc *, int, 124 int, caddr_t, int)); 125 static int wi_seek __P((struct wi_softc *, int, int, int)); 126 static int wi_alloc_nicmem __P((struct wi_softc *, int, int *)); 127 static void wi_inquire __P((void *)); 128 static void wi_wait_scan __P((void *)); 129 static int wi_setdef __P((struct wi_softc *, struct wi_req *)); 130 static int wi_getdef __P((struct wi_softc *, struct wi_req *)); 131 static int wi_mgmt_xmit __P((struct wi_softc *, caddr_t, int)); 132 133 static int wi_media_change __P((struct ifnet *)); 134 static void wi_media_status __P((struct ifnet *, struct ifmediareq *)); 135 136 static void wi_get_id __P((struct wi_softc *)); 137 138 static int wi_set_ssid __P((struct ieee80211_nwid *, u_int8_t *, int)); 139 static void wi_request_fill_ssid __P((struct wi_req *, 140 struct ieee80211_nwid *)); 141 static int wi_write_ssid __P((struct wi_softc *, int, struct wi_req *, 142 struct ieee80211_nwid *)); 143 static int wi_set_nwkey __P((struct wi_softc *, struct ieee80211_nwkey *)); 144 static int wi_get_nwkey __P((struct wi_softc *, struct ieee80211_nwkey *)); 145 static int wi_sync_media __P((struct wi_softc *, int, int)); 146 static int wi_set_pm(struct wi_softc *, struct ieee80211_power *); 147 static int wi_get_pm(struct wi_softc *, struct ieee80211_power *); 148 149 int 150 wi_attach(sc) 151 struct wi_softc *sc; 152 { 153 struct ifnet *ifp = sc->sc_ifp; 154 struct wi_ltv_macaddr mac; 155 struct wi_ltv_gen gen; 156 static const u_int8_t empty_macaddr[ETHER_ADDR_LEN] = { 157 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 158 }; 159 int s; 160 161 s = splnet(); 162 163 callout_init(&sc->wi_inquire_ch); 164 callout_init(&sc->wi_scan_sh); 165 166 /* Make sure interrupts are disabled. */ 167 CSR_WRITE_2(sc, WI_INT_EN, 0); 168 CSR_WRITE_2(sc, WI_EVENT_ACK, 0xFFFF); 169 170 /* Reset the NIC. */ 171 wi_reset(sc); 172 173 memset(&mac, 0, sizeof(mac)); 174 /* Read the station address. */ 175 mac.wi_type = WI_RID_MAC_NODE; 176 mac.wi_len = 4; 177 wi_read_record(sc, (struct wi_ltv_gen *)&mac); 178 memcpy(sc->sc_macaddr, mac.wi_mac_addr, ETHER_ADDR_LEN); 179 180 /* 181 * Check if we got anything meaningful. 182 * 183 * Is it really enough just checking against null ethernet address? 184 * Or, check against possible vendor?
