NAME

bgeBroadcom BCM57xx/BCM590x 10/100/Gigabit Ethernet device

SYNOPSIS

bge* at pci?
brgphy* at mii?
rgephy* at mii?

DESCRIPTION

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 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).
