The 54 * publically available version of the HCF library (the 'HCF Light') is 55 * a) extremely gross, b) lacks certain features, particularly support 56 * for 802.11 frames, and c) is contaminated by the GNU Public License. 57 * 58 * This driver does not use the HCF or HCF Light at all. Instead, it 59 * programs the Hermes controller directly, using information gleaned 60 * from the HCF Light code and corresponding documentation. 61 * 62 * This driver supports the ISA, PCMCIA and PCI versions of the Lucent 63 * WaveLan cards (based on the Hermes chipset), as well as the newer 64 * Prism 2 chipsets with firmware from Intersil and Symbol. 65 */ 66 67 #define WI_HERMES_AUTOINC_WAR /* Work around data write autoinc bug. */ 68 #define WI_HERMES_STATS_WAR /* Work around stats counter bug. */ 69 70 #include "opt_polling.h" 71 72 #include <sys/param.h> 73 #include <sys/endian.h> 74 #include <sys/systm.h> 75 #include <sys/sockio.h> 76 #include <sys/mbuf.h> 77 #include <sys/proc.h> 78 #include <sys/kernel.h> 79 #include <sys/socket.h> 80 #include <sys/module.h> 81 #include <sys/bus.h> 82 #include <sys/random.h> 83 #include <sys/syslog.h> 84 #include <sys/sysctl.h> 85 #include <sys/serialize.h> 86 #include <sys/rman.h> 87 #include <sys/thread2.h> 88 #include <sys/interrupt.h> 89 90 #include <machine/atomic.h> 91 92 #include <net/if.h> 93 #include <net/if_arp.h> 94 #include <net/ethernet.h> 95 #include <net/if_dl.h> 96 #include <net/if_media.h> 97 #include <net/if_types.h> 98 #include <net/ifq_var.h> 99 100 #include <netproto/802_11/ieee80211_var.h> 101 #include <netproto/802_11/ieee80211_ioctl.h> 102 #include <netproto/802_11/ieee80211_radiotap.h> 103 #include <netproto/802_11/if_wavelan_ieee.h> 104 105 #include <netinet/in.h> 106 #include <netinet/in_systm.h> 107 #include <netinet/in_var.h> 108 #include <netinet/ip.h> 109 #include <netinet/if_ether.h> 110 111 #include <net/bpf.h> 112 113 #include <dev/netif/wi/if_wireg.h> 114 #include <dev/netif/wi/if_wivar.h> 115 116 static void wi_start(struct ifnet *);
