The bge driver provides support for various NICs based on the Broadcom BCM570x, 571x, 572x, 575x, 576x, 578x, 5776x and 5778x Gigabit Ethernet controller chips and the 590x and 5779x Fast Ethernet controller chips, including the following:

The bge driver supports IPv4 IP, TCP, and UDP checksum offload for receive, IP checksum offload for transmit, VLAN tag insertion and stripping, as well as a 256-bit multicast hash filter. The BCM5717, BCM5718, BCM5723, BCM5724, BCM5754, BCM5755, BCM5761, BCM5764, BCM5784, BCM5785, BCM5787 and BCM577xx chips also support IPv6 receive TCP/UDP checksum offload.

The BCM5700, BCM5701, BCM5703 and BCM5704 chips are capable of supporting Jumbo frames, which can be configured via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility configures the adapter to receive and transmit Jumbo frames. Using Jumbo frames can greatly improve performance for certain tasks, such as file transfers and data streaming.

The bge driver supports the following media types:

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.
Set 10Mbps operation. The ifconfig(8) mediaopt option can also be used to select either full-duplex or half-duplex modes.
Set 100Mbps (Fast Ethernet) operation. The ifconfig(8) mediaopt option can also be used to select either full-duplex or half-duplex modes.
Set 1000baseT operation over twisted pair. Both full-duplex and half-dupex modes are supported.
Set 1000Mbps (Gigabit Ethernet) operation. Both full-duplex and half-duplex modes are supported.

The bge driver supports the following media options:

Force full duplex operation.
Force half duplex operation.

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