Overview

The bge1g driver provides support for various NICs based on the Broadcom BCM570x, 5714, 5721, 5722, 5750, 5751, 5752 and 5789 families of Gigabit Ethernet controller chips.

The BCM5700, BCM5701, BCM5702, BCM5703 and BCM5704 support jumbo frames. Support for Jumbo Frames is provided via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the ifconfig utility configures the adapter to receive and transmit Jumbo Frames.

The bge1g driver supports the following media types:

• autoselect
  Enables auto-negotiation for speed and duplex.
• 10baseT/UTP
  Sets 10Mbps operation. Use the mediaopt option to select full-duplex mode.
• 100baseTX
  Sets 100Mbps operation. Use the mediaopt option to select full-duplex mode.
• 1000baseSX
  Sets 1000Mbps operation. Only full-duplex mode is supported at this speed.
• 1000baseTX
  Sets 1000Mbps operation. Only full-duplex mode is supported at this speed.

The bge1g driver supports the following media options:

• full-duplex
  Forces full-duplex operation
• half-duplex
  Forces half-duplex operation.

For more information on configuring this device, see Common Network Driver Options or ifconfig.

Diagnostics

Diagnostic messages will be logged to System Evenrt Log.

• bge1g%d: couldn't map memory A fatal initialization error has occurred.
• bge1g%d: couldn't map ports A fatal initialization error has occurred.
• bge1g%d: couldn't map interrupt A fatal initialization error has occurred.
• bge1g%d: no memory for softc struct! The driver failed to allocate memory for per-device instance information during initialization.
• bge1g%d: failed to enable memory mapping! The driver failed to initialize PCI shared memory mapping. This might happen if the card is not in a bus-master slot.
• bge1g%d: no memory for jumbo buffers! The driver failed to allocate memory for jumbo frames during initialization.
• bge1g%d: watchdog timeout The device has stopped responding to the net- work, or there is a problem with the network connection (cable).
