The XMAC provides all of the MAC 111 * components and a PHY while the GEnesis controller provides a PCI 112 * interface with DMA support. Each card may have between 512K and 113 * 2MB of SRAM on board depending on the configuration. 114 * 115 * The SysKonnect GEnesis controller can have either one or two XMAC 116 * chips connected to it, allowing single or dual port NIC configurations. 117 * SysKonnect has the distinction of being the only vendor on the market 118 * with a dual port gigabit ethernet NIC. The GEnesis provides dual FIFOs, 119 * dual DMA queues, packet/MAC/transmit arbiters and direct access to the 120 * XMAC registers. This driver takes advantage of these features to allow 121 * both XMACs to operate as independent interfaces. 122 */ 123 124 #include "bpfilter.h" 125 126 #include <sys/param.h> 127 #include <sys/systm.h> 128 #include <sys/sockio.h> 129 #include <sys/mbuf.h> 130 #include <sys/malloc.h> 131 #include <sys/kernel.h> 132 #include <sys/socket.h> 133 #include <sys/device.h> 134 #include <sys/queue.h> 135 #include <sys/callout.h> 136 137 #include <net/if.h> 138 #include <net/if_dl.h> 139 #include <net/if_types.h> 140 141 #ifdef INET 142 #include <netinet/in.h> 143 #include <netinet/in_systm.h> 144 #include <netinet/in_var.h> 145 #include <netinet/ip.h> 146 #include <netinet/if_ether.h> 147 #endif 148 149 #include <net/if_media.h> 150 151 #if NBPFILTER > 0 152 #include <net/bpf.h> 153 #endif 154 155 #include <dev/mii/mii.h> 156 #include <dev/mii/miivar.h> 157 #include <dev/mii/brgphyreg.h> 158 159 #include <dev/pci/pcireg.h> 160 #include <dev/pci/pcivar.h> 161 #include <dev/pci/pcidevs.h> 162 163 #define SK_VERBOSE 164 /* #define SK_USEIOSPACE */ 165 166 #include <dev/pci/if_skreg.h> 167 #include <dev/pci/if_skvar.h> 168 169 int skc_probe(struct device *, struct cfdata *, void *);
