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:
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
bge%d: can't find mem space A fatal initialization error has occurred.
bge%d: couldn't map interrupt A fatal initialization error has occurred.
bge%d: no memory for jumbo buffer queue! The driver failed to allocate
memory for jumbo frames during initialization.
bge%d: watchdog timeout The device has stopped responding to the
network, or there is a problem with the network connection (cable).
