The bge driver supports IPv4 receive IP/TCP/UDP checksum offload and transmit IP/TCP checksum offload, VLAN tag insertion and stripping, as well as a 256-bit multicast hash filter. The BCM5717, BCM5718, BCM5723, BCM5754, BCM5755, BCM5761, BCM5764, BCM5784, BCM5785, BCM5787 and BCM577xx chips also support IPv6 receive TCP/UDP checksum offload.

The BCM5700, BCM5701, BCM5703, BCM5704, BCM5714, BCM5717, BCM5719, BCM5720, BCM5762, BCM5780, BCM57765 and BCM57766 chips are capable of supporting jumbo frames.

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 adding media options to the appropriate hostname.if(5) file.

10baseT

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.

1000baseT

Set 1000baseT operation over twisted pair. Both full-duplex and half-dupex modes are supported.

1000baseSX

Set 1000Mbps (Gigabit Ethernet) operation. Both full-duplex 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.

For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS

bge0: can't find mem space

A fatal initialization error has occurred.

bge0: couldn't map interrupt

A fatal initialization error has occurred.

bge0: watchdog timeout -- resetting

The device has stopped responding to the network, or there is a problem with the network connection (cable).
