BCE(4) BSD Programmer's Manual BCE(4)NAMEbce - Broadcom BCM4401 Ethernet device driver
SYNOPSIS
bce* at pci? dev ? function ?
DESCRIPTION
The bce provides support for the Broadcom BCM4401 10/100 Ethernet card.
Other cards from the 440x series may also be supported.
The following media types and options (as given to ifconfig(8)) are sup-
ported:
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 au-
toselect 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 oc-
curred.
bce%d: unable to wake up from power state D%d The card has lost its con-
figuration 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 oc-
curred.
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 er-
ror 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 reinitial-
ized.
bce%d: descriptor error An error occurred, the interface will be reini-
tialized.
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 ini-
tialize 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 reset-
ting 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 reset-
ting 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 oc-
curred when reading a PHY register on the MII.
bce%d: PHY read timed out writing phy %d, reg %d, val = %x An error oc-
curred when writing a PHY register on the MII.
