spwr - 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 controllers. Multiple EtherPower II controllers installed within the system are sup- ported by the driver. The spwr driver provides basic support for the SMC EtherPower II hardware. Functions include chip initialization, 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 functionality 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: o The maximum SDU is 1500 ( ETHERMTU). o The minimum SDU is 0. The spwr driver will pad to the mandatory 60-octet minimum packet size. o The DLSAP address length is 8. o The 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 address (FF:FF:FF:FF:FF:FF).

ixgb - SUNWixgb, 10G Gigabit Ethernet driver for Intel 82597ex controllers and Sun Kirkwood adapters SYNOPSIS
/dev/ixgb DESCRIPTION
The ixgb 10Gigabit Ethernet driver is a multi-threaded, loadable, clonable, GLD-based STREAMS driver supporting the Data Link Provider Interface, DLPI, on Intel 82597ex 10 Gigabit Ethernet controllers and Sun 10G Kirkwood adapters. The Intel 10G controller incorporates both MAC and PHY functions and provides 10G (fiber) Ethernet operation on the SR and LR connectors. The Sun Kirkwood adapter is a 133 MHz PCIX 10 Gig Ethernet card utilizing the Intel 82597EX PCIX MAC controller with XFP-based 10GigE optics. The ixgb driver functions include controller initialization, frame transmit and receive, promiscuous and multicast support and error recov- ery and reporting. The ixgb driver and hardware support auto-negotiation, a protocol specified by the 802.ae specification. APPLICATION PROGRAMMING INTERFACE
The cloning character-special device /dev/ixgb is used to access all Intel 10G controllers and Sun Kirkwood adapters installed within the system. The ixgb driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the ixgb driver with the DLPI and STREAMS func- tionality required of a LAN driver. See gld(7D) for more details on supported primitives. You must send an explicit DL_ATTACH_REQ message to associate the opened stream with a particular device (PPA). The PPA ID is interpreted as an unsigned integer data type and indicates the corresponding device instance (unit) number. The driver returns an error (DL_ERROR_ACK) if the PPA field value does not correspond to a valid device instance number for the system. The device is initialized on first attach and de- initialized (stopped) at last detach. The values returned by the driver in the DL_INFO_ACK primitive in response to the DL_INFO_REQ are as follows: o Maximum SDU is 1500 (ETHERMTU - defined in <sys/ethernet.h>). o Minimum SDU is 0. o DLSAP address length is 8. o MAC type is DL_ETHER. o SAP length value is -2 meaning the physical address component is followed immediately by a 2 byte SAP component within the DLSAP address. o Broadcast address value is Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF). Once in the DL_ATTACHED state, you must send a DL_BIND_REQ to associate a particular Service Access Point (SAP) with the stream. By default, the ixgb driver performs auto-negotiation to select the 10G link speed. FILES
