.Sh NAME
.Nm bce
.Nd "Broadcom NetXtreme II (BCM5706/BCM5708) PCI/PCIe Gigabit Ethernet adapter driver"
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device miibus"
.Cd "device bce"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
if_bce_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports Broadcom's NetXtreme II product family, including the
BCM5706 and BCM5708 Ethernet controllers.
.Pp
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 addtion to standard L2 Ethernet traffic, all on the
same controller. The following features are supported in the
.Nm
driver under FreeBSD:
.Bd -literal -offset indent
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
.Ed
.Pp
The
.Nm
driver supports the following media types:
.Bl -tag -width ".Cm 10baseT/UTP"
.It Cm autoselect
Enable autoselection of the media type and options.
The user can manually override
the autoselected mode by adding media options to
.Xr rc.conf 5 .
.It Cm 10baseT/UTP
Set 10Mbps operation.
The
.Xr ifconfig 8
.Ic mediaopt
option can also be used to select either
.Cm full-duplex
or
.Cm half-duplex
modes.
.It Cm 100baseTX
Set 100Mbps (Fast Ethernet) operation.
The
.Xr ifconfig 8
.Ic mediaopt
option can also be used to select either
.Cm full-duplex
or
.Cm half-duplex
modes.
.It Cm 1000baseTX
Set 1000baseTX operation over twisted pair.
Only
.Cm full-duplex
mode is supported.
.El
.Pp
The
.Nm
driver supports the following media options:
.Bl -tag -width ".Cm full-duplex"
.It Cm full-duplex
Force full duplex operation.
.It Cm half-duplex
Force half duplex operation.
.El
.Pp
For more information on configuring this device, see
.Xr ifconfig 8 .
.Sh HARDWARE
