That driver is Copyright (c) 1997 University 98 * of Troms, Norway. It is part of the Linix pcmcia-cs package that 99 * can be found at 100 * http://hyper.stanford.edu/HyperNews/get/pcmcia/home.html. The most 101 * recent version of the pcmcia-cs package when this driver was 102 * written was 3.0.6. 103 * 104 * Unfortunately, a lot of explicit numeric constants were used in the 105 * Linux driver. I have tried to use symbolic names whenever possible, 106 * but since I don't have any real hardware documentation, there's 107 * still one or two "magic numbers" :-(. 108 * 109 * Driver limitations: This driver doesn't do multicasting or receiver 110 * promiscuity, because of missing hardware documentation. I couldn't 111 * get receiver promiscuity to work, and I haven't even tried 112 * multicast. Volunteers are welcome, of course :-). 113 */ 114 115 #include "opt_inet.h" 116 #include "bpfilter.h" 117 118 #include <sys/param.h> 119 #include <sys/systm.h> 120 #include <sys/device.h> 121 #include <sys/socket.h> 122 #include <sys/mbuf.h> 123 #include <sys/ioctl.h> 124 #include <sys/proc.h> 125 126 #include <net/if.h> 127 128 #include <dev/pcmcia/if_cnwreg.h> 129 #include <dev/pcmcia/if_cnwioctl.h> 130 131 #include <dev/pcmcia/pcmciareg.h> 132 #include <dev/pcmcia/pcmciavar.h> 133 #include <dev/pcmcia/pcmciadevs.h> 134 135 #include <net/if_dl.h> 136 #include <net/if_ether.h> 137 138 #ifdef INET 139 #include <netinet/in.h> 140 #include <netinet/in_systm.h> 141 #include <netinet/in_var.h> 142 #include <netinet/ip.h> 143 #include <netinet/if_inarp.h> 144 #endif 145 146 #if NBPFILTER > 0 147 #include <net/bpf.h> 148 #include <net/bpfdesc.h> 149 #endif 150 151 /* 152 * Let these be patchable variables, initialized from macros that can 153 * be set in the kernel config file.
