SYNOPSIS

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


.Cd device miibus
.Cd 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
.Fx :

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).
