dnet - Ethernet driver for DEC 21040, 21041, 21140 Ethernet cards
/kernel/drv/dnet
The dnet Ethernet driver is a multithreaded, loadable, clonable, STREAMS GLD driver. Multiple controllers installed within the system are supported by the driver. The dnet driver functions include controller initialization, frame transmit and receive, functional addresses, promiscuous and multicast support, and error recovery and reporting.
The cloning character-special device, /dev/dnet, is used to access all DEC 21040/21041/21140 devices installed in the system.
The dnet driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the dnet driver with the DLPI and STREAMS functionality required of a LAN driver. See gld(4D) for more details on the primitives supported by the driver.
The device is initialized on the first attach and de-initialized (stopped) on the last detach.
The values returned by the driver in the DL_INFO_ACK primitive in response to a DL_INFO_REQ from the user are as follows:
Once in the DL_ATTACHED state, the user must send a DL_BIND_REQ to associate a particular Service Access Point (SAP) with the stream.
The PCI configuration process varies from system to system. Follow the instructions provided by the vendor.
The /kernel/drv/dnet.conf file supports the following options:
full-duplex
speed
/dev/dnet
/kernel/drv/dnet.conf
