NAME
     bnx -- Broadcom NetXtreme II 10/100/1000 Ethernet device

SYNOPSIS
     bnx* at pci?
     brgphy* at mii?

DESCRIPTION
     The bnx driver supports Broadcom's NetXtreme II product family, such as
     the BCM5706 PCI-X and BCM5708 PCI Express Ethernet controllers, which
     includes the following:

     +   Dell PowerEdge 1950 integrated BCM5708 NIC (10/100/1000baseT)
     +   Dell PowerEdge 2950 integrated BCM5708 NIC (10/100/1000baseT)
     +   HP NC370F PCI-X Multifunction Gigabit server adapter (1000baseSX)
     +   HP NC370T PCI-X Multifunction Gigabit server adapter
         (10/100/1000baseT)
     +   HP NC373F PCI Express Multifunction Gigabit server adapter
         (1000baseSX)
     +   HP NC373i PCI Express Multifunction Gigabit embedded server adapter
         (10/100/1000baseT)
     +   HP NC380T PCI Express Dual Port Multifunction Gigabit server adapter
         (10/100/1000baseT)
     +   IBM xSeries 3550 integrated BCM5708 NIC (10/100/1000baseT)
     +   IBM xSeries 3650 integrated BCM5708 NIC (10/100/1000baseT)

     The NetXtreme II product family is composed of various Converged NIC (or
     CNIC) Ethernet controllers which support a TCP Offload Engine (TOE),
     Remote DMA (RDMA), and iSCSI acceleration, in addition to standard L2
     Ethernet traffic, all on the same controller.  The following features are
     supported in the bnx driver under NetBSD:

           IPv4 receive IP/TCP/UDP checksum offload
           Jumbo frames (up to 9022 bytes)
           VLAN tag insertion
           Interrupt coalescing
           10/100/1000Mbps operation in full-duplex mode
           10/100Mbps operation in half-duplex mode

     The bnx driver supports the following media types:

     autoselect   Enable autoselection of the media type and options.  The
                  user can manually override the autoselected mode via
                  ifconfig(8).

     10baseT/UTP  Set 10Mbps operation.  The ifconfig(8) mediaopt option can
                  also be used to select either full-duplex or half-duplex
                  modes.

     100baseTX    Set 100Mbps (Fast Ethernet) operation.  The ifconfig(8)
                  mediaopt option can also be used to select either
                  full-duplex or half-duplex modes.

     1000baseTX   Set 1000baseTX operation over twisted pair.  Only
                  full-duplex mode is supported.

     The bnx driver supports the following media options:

     full-duplex  Force full duplex operation.

     half-duplex  Force half duplex operation.

     For more information on configuring this device, see ifconfig(8).
