NetBSD 6.1.5 - man page for bnx (netbsd section 4)

BNX(4)				   BSD Kernel Interfaces Manual 			   BNX(4)

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-BCM5709 PCI Express Ethernet controllers, which includes the following:

     o	 Dell PowerEdge 1950 integrated BCM5708 NIC (10/100/1000baseT)
     o	 Dell PowerEdge 2950 integrated BCM5708 NIC (10/100/1000baseT)
     o	 Dell PowerEdge M710 integrated BCM5709S NIC (1000baseSX)
     o	 HP NC370F PCI-X Multifunction Gigabit server adapter (1000baseSX)
     o	 HP NC370T PCI-X Multifunction Gigabit server adapter (10/100/1000baseT)
     o	 HP NC373F PCI Express Multifunction Gigabit server adapter (1000baseSX)
     o	 HP NC373i PCI Express Multifunction Gigabit embedded server adapter (10/100/1000baseT)
     o	 HP NC380T PCI Express Dual Port Multifunction Gigabit server adapter (10/100/1000baseT)
     o	 IBM xSeries 3550 integrated BCM5708 NIC (10/100/1000baseT)
     o	 IBM xSeries 3650 integrated BCM5708 NIC (10/100/1000baseT)

     The NetXtreme II product family is composed of various Converged NIC (or CNIC) Ethernet con-
     trollers which support a TCP Offload Engine (TOE), Remote DMA (RDMA), and iSCSI accelera-
     tion, in addition to standard L2 Ethernet traffic, all on the same controller.  The follow-
     ing 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 sup-
		  ported.

     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).
