Add device driver support for the Broadcom BCM570x family of gigabit

ethernet controllers. This adds support for the 3Com 3c996-T, the
SysKonnect SK-9D21 and SK-9D41, and the built-in gigE NICs on
Dell PowerEdge 2550 servers. The latter configuration hauls ass:
preliminary measurements show TCP speeds of over 900Mbps using
only normal size frames.

TCP/IP checksum offload, jumbo frames and VLAN tag insertion/stripping
are supported, as well as interrupt moderation.

Still need to fix autonegotiation support for 1000baseSX NICs, but
beyond that, driver is pretty solid.

+ * Broadcom BCM570x family gigabit ethernet driver for FreeBSD.
+ * 
+ * Written by Bill Paul <wpaul@windriver.com>
+ * Senior Engineer, Wind River Systems
+ */
+
+/*
+ * The Broadcom BCM5700 is based on technology originally developed by
+ * Alteon Networks as part of the Tigon I and Tigon II gigabit ethernet
+ * MAC chips. The BCM5700, sometimes refered 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 BCM5700
+ * 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.

+ * BCM570x memory map. The internal memory layout varies somewhat
+ * depending on whether or not we have external SSRAM attached.
+ * The BCM5700 can have up to 16MB of external memory. The BCM5701
+ * is apparently not designed to use external SSRAM. The mappings
+ * up to the first 4 send rings are the same for both internal and
+ * external memory configurations. Note that mini RX ring space is
+ * only available with external SSRAM configurations, which means
+ * the mini RX ring is not supported on the BCM5701.
+ *
+ * The NIC's memory can be accessed by the host in one of 3 ways:
+ *
+ * 1) Indirect register access. The MEMWIN_BASEADDR and MEMWIN_DATA
+ *    registers in PCI config space can be used to read any 32-bit
+ *    address within the NIC's memory.
+ *
+ * 2) Memory window access. The MEMWIN_BASEADDR register in PCI config
+ *    space can be used in conjunction with the memory window in the
+ *    device register space at offset 0x8000 to read any 32K chunk
+ *    of NIC memory.
+ *
+ * 3) Flat mode. If the 'flat mode' bit in the PCI state register is
+ *    set, the device I/O mapping consumes 32MB of host address space,
+ *    allowing all of the registers and internal NIC memory to be
+ *    accessed directly. NIC memory addresses are offset by 0x01000000.
+ *    Flat mode consumes so much host address space that it is not
+ *    recommended.
