The BCM5700, sometimes referred to as the Tigon III, has 43 * two on-board MIPS R4000 CPUs and can have as much as 16MB of external 44 * SSRAM. The BCM5700 supports TCP, UDP and IP checksum offload, jumbo 45 * frames, highly configurable RX filtering, and 16 RX and TX queues 46 * (which, along with RX filter rules, can be used for QOS applications). 47 * Other features, such as TCP segmentation, may be available as part 48 * of value-added firmware updates. Unlike the Tigon I and Tigon II, 49 * firmware images can be stored in hardware and need not be compiled 50 * into the driver. 51 * 52 * The BCM5700 supports the PCI v2.2 and PCI-X v1.0 standards, and will 53 * function in a 32-bit/64-bit 33/66Mhz bus, or a 64-bit/133Mhz bus. 54 * 55 * The BCM5701 is a single-chip solution incorporating both the BCM5700 56 * MAC and a BCM5401 10/100/1000 PHY. Unlike the BCM5700, the BCM5701 57 * does not support external SSRAM. 58 * 59 * Broadcom also produces a variation of the BCM5700 under the "Altima" 60 * brand name, which is functionally similar but lacks PCI-X support. 61 * 62 * Without external SSRAM, you can only have at most 4 TX rings, 63 * and the use of the mini RX ring is disabled. This seems to imply 64 * that these features are simply not available on the BCM5701. As a 65 * result, this driver does not implement any support for the mini RX 66 * ring. 67 */ 68 69 #ifdef HAVE_KERNEL_OPTION_HEADERS 70 #include "opt_device_polling.h" 71 #endif 72 73 #include <sys/param.h> 74 #include <sys/endian.h> 75 #include <sys/systm.h> 76 #include <sys/sockio.h> 77 #include <sys/mbuf.h> 78 #include <sys/malloc.h> 79 #include <sys/kernel.h> 80 #include <sys/module.h> 81 #include <sys/socket.h> 82 #include <sys/sysctl.h> 83 #include <sys/taskqueue.h> 84 85 #include <net/if.h> 86 #include <net/if_arp.h> 87 #include <net/ethernet.h> 88 #include <net/if_dl.h> 89 #include <net/if_media.h> 90 91 #include <net/bpf.h> 92 93 #include <net/if_types.h> 94 #include <net/if_vlan_var.h> 95 96 #include <netinet/in_systm.h> 97 #include <netinet/in.h> 98 #include <netinet/ip.h> 99 #include <netinet/tcp.h> 100 101 #include <machine/bus.h> 102 #include <machine/resource.h> 103 #include <sys/bus.h> 104 #include <sys/rman.h> 105 106 #include <dev/mii/mii.h> 107 #include <dev/mii/miivar.h> 108 #include "miidevs.h" 109 #include <dev/mii/brgphyreg.h> 110 111 #ifdef __sparc64__ 112 #include <dev/ofw/ofw_bus.h> 113 #include <dev/ofw/openfirm.h> 114 #include <machine/ofw_machdep.h> 115 #include <machine/ver.h> 116 #endif 117 118 #include <dev/pci/pcireg.h> 119 #include <dev/pci/pcivar.h> 120 121 #include <dev/bge/if_bgereg.h> 122 123 #define BGE_CSUM_FEATURES (CSUM_IP | CSUM_TCP) 124 #define ETHER_MIN_NOPAD (ETHER_MIN_LEN - ETHER_CRC_LEN) /* i.e., 60 */ 125 126 MODULE_DEPEND(bge, pci, 1, 1, 1); 127 MODULE_DEPEND(bge, ether, 1, 1, 1); 128 MODULE_DEPEND(bge, miibus, 1, 1, 1); 129 130 /* "device miibus" required.
