     The bge driver supports IPv4 IP, TCP, and UDP checksum offload for re-
     ceive, IP checksum offload for transmit, VLAN tag insertion and strip-
     ping, as well as a 256-bit multicast hash filter.  The BCM5723, BCM5754,
     BCM5755, BCM5761, BCM5764, BCM5784, BCM5785, BCM5787 and BCM577x0 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.  Se-
     lecting an MTU larger than 1500 bytes with the ifconfig(8) utility con-
     figures 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 net-
     work, or there is a problem with the network connection (cable).
