bge - Broadcom BCM570x PCI Gigabit Ethernet adapter driver
bge* at pci? dev ? function ?
The bge driver provides support for various NICs based on
BCM570x family of Gigabit Ethernet controller chips, including the following:
+o 3Com 3c996-T
+o 3Com 3c996-SX
+o 3Com 3c996B-T
+o Dell PowerEdge 2550 integrated BCM5700 NIC
+o IBM xSeries 235 integrated BCM5703X NIC
+o IBM xSeries 305 integrated BCM5703X NIC
+o Netgear GA302T
+o SysKonnect SK-9D21
+o SysKonnect SK-9D41
All of these NICs are capable of 10, 100 and 1000Mbps speeds
copper cable, except for the SysKonnect SK-9D41 which supports only
1000Mbps over multimode fiber. It has two R4000 CPU cores
and is PCI
v2.2 and PCI-X v1.0 compliant. It supports multiple RX and
TX DMA rings
for QoS applications, rules-based receive filtering, and
VLAN tag stripping/insertion
as well as a 256-bit multicast hash filter.
features may be provided via value-add firmware updates.
supports TBI (ten bit interface) and GMII transceivers,
which means it
can be used with either copper of 1000baseX fiber applications. Note
however the device only supports a single speed in TBI mode.
Most cards also use the Broadcom BCM5401 or BCM5411
gigabit transceivers, which support autonegotiation of 10,
1000Mbps modes in full or half duplex.
The bge driver supports the following media types:
autoselect Enable autoselection of the media type and options. The user
can manually override the autoselected mode by
options to the appropriate hostname.if(5) file.
10baseT Set 10Mbps operation. The ifconfig(8) mediaopt
also be used to select either full-duplex or
100baseTX Set 100Mbps (Fast Ethernet) operation. The ifconfig(8)
mediaopt option can also be used to select either full-duplex
or half-duplex modes.
1000baseT Set 1000baseT operation over twisted pair.
half-duplex modes are supported.
1000baseSX Set 1000Mbps (Gigabit Ethernet) operation. Both
and half-duplex modes are supported.
The bge driver supports the following media options:
full-duplex Force full duplex operation.
half-duplex Force half duplex operation.
The bge driver also supports one special link option for
link0 With 1000baseT cards, establishing a link between two
that one port be configured as a master and
the other a
slave. With autonegotiation, the master/slave settings will be
chosen automatically. However when manually selecting the link
state, it is necessary to force one side of the link
to be a master
and the other a slave. The bge driver configures
the ports as
slaves by default. Setting the link0 flag with ifconfig(8) will
set a port as a master instead.
For more information on configuring this device, see ifconfig(8).
