NAME

     bce — QLogic NetXtreme II (BCM5706/5708/5709/5716) PCI/PCIe Gigabit Ethernet adapter driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel
     configuration file:

           device miibus
           device bce

     Alternatively, to load the driver as a module at boot time, place the following line in
     loader.conf(5):

           if_bce_load="YES"

DESCRIPTION

     The bce driver supports QLogic's NetXtreme II product family, including the BCM5706,
     BCM5708, BCM5709 and BCM5716 Ethernet controllers.

     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 bce driver under FreeBSD:

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

     The bce driver supports the following media types:

     autoselect   Enable autoselection of the media type and options.  The user can manually
                  override the autoselected mode by adding media options to rc.conf(5).

     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.

     1000baseSX   Sets 1000Mbps operation.  Only full-duplex mode is supported at this speed.

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

     2500BaseSX   Set 2500Mbps operation.  Only full-duplex mode is supported.

     The bce 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).
