ntxn - NetXen 10/1 Gigabit Ethernet network driver SYNOPSIS
/dev/ntxn* DESCRIPTION
The ntxn 10/1 Gigabit Ethernet driver is a multi-threaded, loadable, clonable, GLD-based STREAMS driver supporting the Data Link Provider Interface, dlpi(7P), on NetXen 10/1 Gigabit Ethernet controllers. The ntxn driver functions include chip initialization, frames transmit and receive, promiscuous and multicast support, TCP and UDP checksum off-load (IPv4) and 9600 bytes jumbo frame. The ntxn driver and hardware support the 10GBASE CX4, 10GBASE-SR/W, LR/W, and 10/100/1000BASE-T physical layers. APPLICATION PROGRAMMING INTERFACE
The cloning character-special device, /dev/ntxn, is used to access all NetXen devices installed within the system. The ntxn driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of ntxn instances and for ntxn instances to be aggregated. See dladm(1M) for more details. The values returned by the driver in the DL_INFO_ACK primitive in response to your DL_INFO_REQ are: o Maximum SDU is 9600. o Minimum SDU is 0. o DLSAP address length is 8. o MAC type is DL_ETHER. o SAP (Service Access Point) 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 the Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF). CONFIGURATION
By default, the ntxn driver works without any configuration file. FILES

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
