NAME
     bce - Broadcom BCM4401 10/100 Ethernet device

SYNOPSIS
     bce* at pci?
     bmtphy* at mii?

DESCRIPTION
     The bce provides support for the Broadcom BCM4401 10/100 Ethernet card.

     The following media types and options (as given to ifconfig(8)) are
     supported:

	   media autoselect
		Enable autoselection of the media type and options (default).

	   media 100baseTX mediaopt full-duplex
		Set 100Mbps (Fast Ethernet) operation and force full-duplex
		mode.

	   media 100baseTX mediaopt half-duplex
		Set 100Mbps (Fast Ethernet) operation and force half-duplex
		mode.

	   media 10baseT mediaopt full-duplex
		Set 10Mbps operation and force full-duplex.

	   media 10baseT mediaopt half-duplex
		Set 10Mbps operation and force half-duplex.

     If no media options are present, the bce driver places the card into
     autoselect mode.

DIAGNOSTICS
     bce%d: failed to enable memory mapping!  A fatal initialization error has
     occurred.

     bce%d: unable to find mem space  A fatal initialization error has
     occurred.

     bce%d: unable to wake up from power state D%d  The card has lost its
     configuration data during power save mode.

     bce%d: couldn't map interrupt  A fatal initialization error has occurred.

     bce%d: couldn't establish interrupt  A fatal initialization error has
     occurred.

     bce%d: unable to alloc space for ring descriptors, error = %d  A fatal
     initialization error has occurred.

     bce%d: unable to map DMA buffers, error = %d  A fatal initialization
     error has occurred.

     bce%d: unable to create ring DMA map, error = %d  A fatal initialization
     error has occurred.

     bce%d: unable to create tx DMA map, error = %d  A fatal initialization
     error has occurred.

     bce%d: unable to create rx DMA map, error = %d  A fatal initialization
     error has occurred.

     bce%d: Tx packet consumes too many DMA segments, dropping...  An outgoing
     packet didn't fit in the allocated number of segments.

     bce%d: unable to load Tx buffer, error = %d  Short on resources when
     transmitting a packet, it will be retried later.

     bce%d: device timeout  The device has stopped responding to the network
     or there is a problem with the network connection (cable).

     bce%d: transmit fifo underflow  An error occurred, the interface will be
     reinitialized.

     bce%d: receive fifo overflow  An error occurred, the interface will be
     reinitialized.

     bce%d: receive descriptor underflow  An error occurred, the interface
     will be reinitialized.

     bce%d: descriptor protocol error  An error occurred, the interface will
     be reinitialized.

     bce%d: data error	An error occurred, the interface will be
     reinitialized.

     bce%d: descriptor error  An error occurred, the interface will be
     reinitialized.

     bce%d: general purpose timeout  An error occurred, the interface will be
     reinitialized.

     bce%d: unable to allocate or map rx(%d) mbuf, error = %d  Failed to
     initialize the interface.

     bce%d: timed out writing pkt filter ctl  Failed to add MAC address.

     bce%d: timed out disabling ethernet mac  A problem occurred when
     resetting the interface.

     bce%d: receive dma did not go idle after error  A problem occurred when
     resetting the interface.

     bce%d: timed out resetting ethernet mac  A problem occurred when
     resetting the interface.

     bce%d: while resetting core, reject did not set  A problem occurred when
     resetting the interface.

     bce%d: while resetting core, busy did not clear  A problem occurred when
     resetting the interface.

     bce%d: PHY read timed out reading phy %d, reg %d, val = %x	 An error
     occurred when reading a PHY register on the MII.

     bce%d: PHY read timed out writing phy %d, reg %d, val = %x	 An error
     occurred when writing a PHY register on the MII.

HISTORY
     The bce driver appeared in NetBSD 1.6.2.  OpenBSD support was added in
     OpenBSD 3.5.

AUTHORS
     The bce driver was written by Cliff Wright <cliff@snipe444.org> and
     ported to OpenBSD by Nathan L. Binkert <binkertn@umich.edu>.

BUGS
     The BCM4401 hardware can not do DMA to addresses above 1GB.  Since the
     bce driver makes no effort to circumvent this problem, it is likely that
     the device will not work properly on machines with more than 1GB of
     system memory.
