NAME

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


SYNOPSIS

     bnx* at pci?

DESCRIPTION

     The bnx driver supports Broadcom's NetXtreme II product family, such as
     the BCM5706 PCI-X and BCM5708-BCM5709-BCM5716 PCIe Ethernet controllers,
     which includes the following:

     ·   Dell PowerEdge 1950 integrated BCM5708 NIC (10/100/1000baseT)
     ·   Dell PowerEdge 2950 integrated BCM5708 NIC (10/100/1000baseT)
     ·   Dell PowerEdge M710 integrated BCM5709S NIC (1000baseSX)
     ·   Dell PowerEdge R710 integrated BCM5709 NIC
     ·   HP NC370F PCI-X Multifunction Gigabit server adapter (1000baseSX)
     ·   HP NC370T PCI-X Multifunction Gigabit server adapter
         (10/100/1000baseT)
     ·   HP NC370i Multifunction Gigabit Server Adapter
     ·   HP NC371i Multifunction Gigabit Server Adapter
     ·   HP NC373F PCIe Multifunction Gigabit server adapter (1000baseSX)
     ·   HP NC373T PCIe Multifunction Gigabit server adapter
         (10/100/1000baseT)
     ·   HP NC373i PCIe Multifunction Gigabit embedded server adapter
         (10/100/1000baseT)
     ·   HP NC373m Multifunction Gigabit Server Adapter
     ·   HP NC374m PCIe Multifunction Gigabit embedded server adapter
         (10/100/1000baseT)
     ·   HP NC380T PCIe Dual Port Multifunction Gigabit server adapter
         (10/100/1000baseT)
     ·   HP NC382T PCIe Dual Port server adapter (10/100/1000baseT)
     ·   HP NC382i DP Multifunction Gigabit Server Adapter
     ·   HP NC382m DP 1GbE Multifunction BL-c Adapter
     ·   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.

     1000baseSX   Set 1000Mbps (Gigabit Ethernet) operation.  Both full-duplex
                  and half-duplex modes are supported.

     2500baseSX   Set 2500Mbps operation.  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).

HISTORY

     The bnx driver was written by David Christensen <davidch@broadcom.com> in
     FreeBSD, where it is called bce.  And it's ported to OpenBSD by Brad
     Smith <brad@openbsd.org>.  It's ported to NetBSD by Quentin Garnier.  The
     bnx device driver first appeared in NetBSD 4.0.

NetBSD 10.1                     March 27, 2019                     NetBSD 10.1
