cs -- Ethernet device driver


     device cs

     In /boot/device.hints:


     The cs driver provides support for ISA Ethernet adapters based on the
     Crystal Semiconductor CS8900 and CS8920 NICs.  These devices are used on
     the IBM EtherJet ISA adapters and in many embedded applications where the
     high integration, small size and low cost of the CS89x0 family compensate
     for their drawbacks.

     The cs driver will obtain configuration parameters either from
     /boot/device.hints or from the card.  At least the I/O port number must
     be specified.  Other parameters specified in /boot/device.hints will be
     used if present; the card may be soft-configured so these may be any
     valid value.  Adapters based on the CS8920 normally offer PnP configura-
     tion and the driver will detect the IBM EtherJet and the CSC6040 adapters

     Note that the CS8900 is limited to 4 IRQ values; these are normally
     implemented as 5, 10, 11 and 12.  The CS8920 has no such limitation.

     Memory-mapped and DMA operation are not supported at this time.


     cs%d: full/half duplex negotiation timeout  The attempt to negotiate
     duplex settings with the hub timed out.  This may indicate a cabling
     problem or a faulty or incompatible hub.

     cs%d: failed to enable <media>  The CS89x0 failed to select the nominated
     media, either because it is not present or not operating correctly.

     cs%d: No EEPROM, assuming defaults  The CS89x0 does not have an EEPROM,
     or the EEPROM is hopelessly damaged.  Operation will only be successful
     if the configuration entry lists suitable values for the adapter.

     cs%d: Invalid irq	The IRQ specified in the configuration entry is not
     valid for the adapter.

     cs%d: Could not allocate memory for NIC  There is a critical memory
     shortage.	The adapter will not function.

     cs%d: Adapter has no media  The adapter is not configured for a specific
     media type.  The media type will have to be manually set.

     This is a %s, but LDN %d is disabled  The PnP probe code found a recog-
     nised adapter, but the adapter is disabled.

     failed to read pnp parms  A PnP adapter was found, but configuration
     traffic.  In particular, NFS operations should be limited to 1k
     read/write transactions in order to avoid overruns.
