NAME

eepro - Intel EtherExpress-Pro Ethernet device driver

SYNOPSIS

/dev/eepro

DESCRIPTION

The eepro Ethernet driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link Provider Interface, dlpi(7P), over Intel EtherExpress-Pro Ethernet controllers. The EtherExpress-Pro Ethernet adapter is based on the Intel 82595TX high integration controller. Multiple EtherExpress-Pro controllers installed within the system are supported by the driver.

The eepro driver provides basic support for the EtherExpress-Pro hardware. Functions including chip initialization, frame transmit and receive, multicast and "promiscuous" support, and error recovery and reporting. It also supports an ioctl to perform a time domain reflectometry test (i.e. detect open or short circuits on the link). Refer to IOCTLS below.

APPLICATION PROGRAMMING

The cloning, character-special device /dev/eepro is used to access all EtherExpress-Pro devices installed within the system.

INTERFACE

eepro and DLPI

The eepro driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the eepro 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 - defined in <sys/ethernet.h>).

The minimum SDU is 0 . The driver will pad to the mandatory 60-byte minimum packet size.

The dlsap address length is 8 .

The Media Access Control (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).

CONFIGURATION

Auto-detect of the media type is supported and the board need not be explicitly configured for which media connector it is using. It is important to ensure that there are no conflicts between the board's I/O port or IRQ level and other hardware installed in the system.
