chxge - Chelsio Ethernet network interface controllers SYNOPSIS
/dev/chxge DESCRIPTION
The chxge Ethernet driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link Provider Interface, dlpi(7P), over Chelsio NIC controllers. Multiple (and mixed) NIC controllers installed within the system are sup- ported by the driver. The chxge driver provides basic support for the NIC hardware. Functions include chip initialization, frame transmit and receive, and error recovery and reporting. APPLICATION PROGRAMMING INTERFACE
The cloning, character-special device /dev/chxge is used to access NIC devices installed within the system. CHXGE AND DLPI
The chxge driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the chxge 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 are: o Default Maximum SDU is 1500 (ETHERMTU). o dlsap address length is 8. o 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 Broadcast address value is Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).

ntxn(7D) Devices ntxn(7D) NAME
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
