The XMAC provides all of the MAC 111 1.10.2.2 skrll * components and a PHY while the GEnesis controller provides a PCI 112 1.10.2.2 skrll * interface with DMA support. Each card may have between 512K and 113 1.10.2.2 skrll * 2MB of SRAM on board depending on the configuration. 114 1.10.2.2 skrll * 115 1.10.2.2 skrll * The SysKonnect GEnesis controller can have either one or two XMAC 116 1.10.2.2 skrll * chips connected to it, allowing single or dual port NIC configurations. 117 1.10.2.2 skrll * SysKonnect has the distinction of being the only vendor on the market 118 1.10.2.2 skrll * with a dual port gigabit ethernet NIC. The GEnesis provides dual FIFOs, 119 1.10.2.2 skrll * dual DMA queues, packet/MAC/transmit arbiters and direct access to the 120 1.10.2.2 skrll * XMAC registers. This driver takes advantage of these features to allow 121 1.10.2.2 skrll * both XMACs to operate as independent interfaces. 122 1.10.2.2 skrll */ 123 1.10.2.8 skrll 124 1.10.2.2 skrll #include "bpfilter.h" 125 1.10.2.2 skrll 126 1.10.2.2 skrll #include <sys/param.h> 127 1.10.2.2 skrll #include <sys/systm.h> 128 1.10.2.2 skrll #include <sys/sockio.h> 129 1.10.2.2 skrll #include <sys/mbuf.h> 130 1.10.2.2 skrll #include <sys/malloc.h> 131 1.10.2.2 skrll #include <sys/kernel.h> 132 1.10.2.2 skrll #include <sys/socket.h> 133 1.10.2.2 skrll #include <sys/device.h> 134 1.10.2.2 skrll #include <sys/queue.h> 135 1.10.2.2 skrll #include <sys/callout.h> 136 1.10.2.2 skrll 137 1.10.2.2 skrll #include <net/if.h> 138 1.10.2.2 skrll #include <net/if_dl.h> 139 1.10.2.2 skrll #include <net/if_types.h> 140 1.10.2.2 skrll 141 1.10.2.2 skrll #ifdef INET 142 1.10.2.2 skrll #include <netinet/in.h> 143 1.10.2.2 skrll #include <netinet/in_systm.h> 144 1.10.2.2 skrll #include <netinet/in_var.h> 145 1.10.2.2 skrll #include <netinet/ip.h> 146 1.10.2.2 skrll #include <netinet/if_ether.h> 147 1.10.2.2 skrll #endif 148 1.10.2.2 skrll 149 1.10.2.2 skrll #include <net/if_media.h> 150 1.10.2.2 skrll 151 1.10.2.2 skrll #if NBPFILTER > 0 152 1.10.2.2 skrll #include <net/bpf.h> 153 1.10.2.2 skrll #endif 154 1.10.2.2 skrll 155 1.10.2.2 skrll #include <dev/mii/mii.h> 156 1.10.2.2 skrll #include <dev/mii/miivar.h> 157 1.10.2.2 skrll #include <dev/mii/brgphyreg.h> 158 1.10.2.2 skrll 159 1.10.2.2 skrll #include <dev/pci/pcireg.h> 160 1.10.2.2 skrll #include <dev/pci/pcivar.h> 161 1.10.2.2 skrll #include <dev/pci/pcidevs.h> 162 1.10.2.2 skrll 163 1.10.2.2 skrll #define SK_VERBOSE 164 1.10.2.2 skrll /* #define SK_USEIOSPACE */ 165 1.10.2.2 skrll 166 1.10.2.2 skrll #include <dev/pci/if_skreg.h> 167 1.10.2.2 skrll #include <dev/pci/if_skvar.h> 168 1.10.2.2 skrll 169 1.10.2.2 skrll int skc_probe(struct device *, struct cfdata *, void *);
