/dev/nfe
The nfe Ethernet driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link Provider Interface, dlpi(7P), over Compaq Netflex-2 controllers. Multiple Netflex-2 controllers installed within the system are supported by the driver. The nfe driver provides basic support for the Netflex-2 hardware. Functions include chip initialization, frame transmit and receive, multicast support, and error recovery and reporting. NOTE: Promiscuous mode is not supported using the current revision of the firmware.
The cloning, character-special device /dev/nfe is used to access all Netflex-2 devices installed within the system.
The nfe driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the nfe driver with the DLPI and STREAMS functionality required of a LAN driver. See gld(7D) for more details on the primatives supported by the driver.
The values returned by the driver in the DL_INFO_ACK primitive in response to the DL_INFO_REQ from the user are as follows:
The maximum SDU is 1500 (ETHERMTU).
The minimum SDU is 0. The driver will pad to the mandatory 60-octet minimum packet size.
The dlsap address length is 8.
The MAC type is DL_ETHER.
The sap length value is -2, meaning the physical address component is followed immediately by a 2-byte sap component within the DLSAP address.
The service mode is DL_CLDLS.
The broadcast address value is Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).
The nfe driver does not support the use of shared RAM on the board. Auto-detect of the media type is also not supported and the board has to be explicitly configured for which media connector it is using.
