DESCRIPTION

The smcf Ethernet driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link Provider Interface over an SMC Ether100 (9232) Fast Ethernet EISA-bus adapter. The smcf driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the smcf driver with the DLPI and STREAMS functionality required of a LAN driver. See gld(7D) for more details about primitives supported by the smcf driver.

The smcf driver provides basic support for the SMC Ether100 hardware. Functions include chip initialization, frame transmission and reception, multicast and promiscuous support, and error recovery and reporting.

Multiple SMC Ether100 controllers installed within the system are supported by the driver.

APPLICATION PROGRAMMING INTERFACE

The cloning character-special device /dev/smcf is used to access all SMC Elite32 Ultra controllers installed within the system.

The values returned by the driver in the DL_INFO_ACK primitive in response to the DL_INFO_REQ from the user are:

• The maximum SDU is 1500 ( ETHERMTU ).

• The minimum SDU is 0. Note that the smcf driver will pad to the mandatory 60-octet minimum packet size.

• The dlsap address length is ETHERADDRL + 2.

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 broadcast address value is Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF). The smcf driver can support up to 16 multicast addresses on each adapter.

CONFIGURATION

The driver is shipped configured to support any legal device configuration. See the SMC Ether100 (9232) Device Configuration page in the x86 Device Configuration Guide for information regarding hardware configuration.
