ieef - Intel Ethernet device driver
The ieef driver currently supports the Intel EtherExpress
Flash (ISA) and Intel 82256 EEpro100 Ethernet (PCI) network
The ieef Ethernet driver is a multi-threaded, loadable,
clonable, STREAMS hardware driver supporting the connection-
less Data Link Provider Interface, dlpi(7P). Multiple con-
trollers 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 sup-
port, 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
The values returned by the driver in the DL_INFO_ACK primi-
tive in response to the DL_INFO_REQ from the user are as
o Maximum SDU is 1500 (ETHERMTU).
o Minimum SDU is 0. The driver will pad to the mandatory
60-octet minimum packet size.
o The dlsap address length is 8.
o MAC type is DL_ETHER.
o The sap length value is -2, meaning the physical
address component is followed immediately by a 2-byte
sap component within the DLSAP address.
o The broadcast address value is Ethernet/IEEE broadcast
Known Problems and Limitations
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.
The /kernel/drv/ieef.conf file supports the ioaddr and intr
