The BCM5700, sometimes referred to as the Tigon III, has * two on-board MIPS R4000 CPUs and can have as much as 16MB of external * SSRAM. The BCM5700 supports TCP, UDP and IP checksum offload, jumbo * frames, highly configurable RX filtering, and 16 RX and TX queues * (which, along with RX filter rules, can be used for QOS applications). * Other features, such as TCP segmentation, may be available as part * of value-added firmware updates. Unlike the Tigon I and Tigon II, * firmware images can be stored in hardware and need not be compiled * into the driver. * * The BCM5700 supports the PCI v2.2 and PCI-X v1.0 standards, and will * function in a 32-bit/64-bit 33/66Mhz bus, or a 64-bit/133Mhz bus. * * The BCM5701 is a single-chip solution incorporating both the BCM5700 * MAC and a BCM5401 10/100/1000 PHY. Unlike the BCM5700, the BCM5701 * does not support external SSRAM. * * Broadcom also produces a variation of the BCM5700 under the "Altima" * brand name, which is functionally similar but lacks PCI-X support. * * Without external SSRAM, you can only have at most 4 TX rings, * and the use of the mini RX ring is disabled. This seems to imply * that these features are simply not available on the BCM5701. As a * result, this driver does not implement any support for the mini RX * ring. */ #ifdef HAVE_KERNEL_OPTION_HEADERS #include "opt_device_polling.h" #endif #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include "miidevs.h" #include #include #include #include #define BGE_CSUM_FEATURES (CSUM_IP | CSUM_TCP) #define ETHER_MIN_NOPAD (ETHER_MIN_LEN - ETHER_CRC_LEN) /* i.e., 60 */ MODULE_DEPEND(bge, pci, 1, 1, 1); MODULE_DEPEND(bge, ether, 1, 1, 1); MODULE_DEPEND(bge, miibus, 1, 1, 1); /* "device miibus" required.
