LNC(4) FreeBSD/i386 Kernel Interfaces Manual LNC(4) NAME lnc -- AMD Lance/PCnet Ethernet device driver SYNOPSIS device lnc0 at isa? port 0x280 irq 10 drq 0 DESCRIPTION The lnc driver provides support for the AMD family of Lance/PCnet Ether- net NICs including the Am7990 and Am79C960. The Ethernet cards supported by the lnc interface are: Novell NE2100 Novell NE32-VL Isolan BICC Digital DEPCA Hewlett Packard Vectra 486/66XM Hewlett Packard Vectra XU Diamond HomeFree DIAGNOSTICS lnc%d: Framing error A framing error occurred. This means a CRC error also occurred. This caused the driver to drop the packet that contained the framing error. lnc%d: Receive CRC error The received Ethernet frame failed the CRC checksum. This caused the driver to drop the packet that failed the checksum. lnc%d: Packet dropped, no mbufs The driver ran out of mbuf's. This may suggest a resource problem. lnc%d: Couldn't allocate memory for NIC This is a fatal error. The driver will not attach to the card under this circumstance. lnc%d: Memory allocated above 16Mb limit ISA and ESIA cards require bounce buffers for DMA transfers above 16mb. The Am7990 and Am79C960 only have 24 address lines and so can only access the lower 16Mb of phys- ical memory. The lnc driver assumes the memory it allocates is within the lower 16Mb range. This is not a very valid assumption but there's nothing that can be done about it yet. For shared memory NICs this isn't relevant. lnc%d: Device timeout -- Resetting The device has stopped responding to the network, or there is a problem with the network connection (cable). Make sure the network connection in use is the same one the card is con- figured for. lnc%d: Transmit late collision -- Net error? lnc%d: Loss of carrier during transmit -- Net error? lnc%d: Transmit of packet failed after 16 attempts -- TDR = %d lnc%d: Heartbeat error -- SQE test failed lnc%d: Babble error - more than 1519 bytes transmitted lnc%d: Missed packet -- no receive buffer lnc%d: Memory error -- Resetting lnc%d: Couldn't get mbuf for transmit packet -- Resetting lnc%d: Receive buffer error lnc%d: Receive overflow error lnc%d: Receive interrupt with buffer still owned by controller -- Resetting lnc%d: Receive interrupt but not start of packet -- Resetting lnc%d: Start of packet found before end of previous in receive ring -- Resetting lnc%d: End of received packet not found -- Resetting lnc%d: Transmit interrupt with buffer still owned by controller -- Resetting lnc%d: Transmit interrupt but not start of packet -- Resetting lnc%d: Start of packet found before end of previous in transmit ring -- Resetting lnc%d: End of transmitted packet not found -- Resetting lnc%d: Transmit buffer error -- Resetting lnc%d: Transmit underflow error -- Resetting BUGS This driver has the potential of being the most verbose of any of the Ethernet device drivers. SEE ALSO arp(4), netintro(4), ng_ether(4), ifconfig(8) HISTORY The lnc device driver first appeared in FreeBSD 2.2. AUTHORS The lnc device driver was written by Paul Richards. Support for the AMD PCHome phone-line based network added by Robert Watson. This manual page was written by David E. O'Brien. FreeBSD 11.1 January 19, 1997 FreeBSD 11.1
