The ieef driver currently supports the Intel EtherExpress Flash (ISA) and Intel 82256 EEpro100 Ethernet (PCI) network cards.
The ieef Ethernet driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link Provider Interface, dlpi(7P). Multiple controllers installed within the system are supported by the driver. The ieef driver provides basic support for the hardware. Functions include chip initialization, frame transmit and receive, multicast and promiscuous mode support, and error recovery and reporting.
The cloning, character-special device /dev/ieef is used to access all Intel devices installed within the system.
The ieef driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the ieef 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:
Maximum SDU is 1500 (ETHERMTU).
Minimum SDU is 0. The driver will pad to the mandatory 60-octet minimum packet size.
The dlsap address length is 8.
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 broadcast address value is Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).
The ieef driver provides 100-Mbps Ethernet support. Note that the driver does not currently transfer data at rates expected of a 100-Mbps interface.
