spwr(7D) Devices spwr(7D)NAMEspwr - SMC EtherPower II 10/100 (9432) Ethernet device driver
SYNOPSIS
/dev/spwr
DESCRIPTION
The spwr Ethernet driver is a multi-threaded, loadable, clonable,
STREAMS hardware driver supporting the connectionless Data Link
Provider Interface, dlpi(7P), over SMC EtherPower II 10/100 con‐
trollers. Multiple EtherPower II controllers installed within the sys‐
tem are supported by the driver. The spwr driver provides basic sup‐
port for the SMC EtherPower II hardware. Functions include chip ini‐
tialization, frame transmit and receive, multicast support, and error
recovery and reporting.
APPLICATION PROGRAMMING INTERFACE
The cloning character-special device /dev/spwr is used to access all
SMC EtherPower II devices installed within the system.
The spwr driver is dependent on /kernel/misc/gld, a loadable kernel
module that provides the spwr driver with the DLPI and STREAMS func‐
tionality required of a LAN driver. See gld(7d) for more details on
the primitives 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 spwr 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 compo‐
nent 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).
