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

rge - Realtek Gigabit/Fast Ethernet Network Adapter driver SYNOPSIS
/dev/rge DESCRIPTION
The rge Gigabit/Fast Ethernet driver is a multi-threaded, loadable, clonable, GLD-based STREAMS driver supporting the Data Link Provider Interface, dlpi(7P), on the Realtek Gigabit/Fast Ethernet Network Adapter. The rge driver functions includes controller initialization, frame transmit and receive, promiscuous and multicast support, and error recovery and reporting. APPLICATION PROGRAMMING INTERFACE
The cloning, character-special device /dev/rge is used to access all Realtek Gigabit/Fast Ethernet devices installed within the system. The rge driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of rge instances and for rge 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 the DL_INFO_REQ are as follows: o Maximum SDU (with jumbo frame) is 7000. o Minimum SDU is 0. o DSLAP address length is 8 bytes. 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. CONFIGURATION
By default, the rge driver performs auto-negotiation to select the link speed and mode. Link speed and mode can be any one of the follow- ing: o 1000 Mbps, full-duplex o 100 Mbps, full-duplex o 100 Mbps, half-duplex o 10 Mbps, full-duplex o 10 Mbps, half-duplex Alternatively, you can set the capabilities advertised by the rge device using ndd(1M). The driver supports a number of parameters whose names begin with adv_. Each of these parameters contains a boolean value that determines if the device advertises that mode of operation. The adv_pause_cap indicates if half/full duplex pause is advertised to link partner. You can set adv_asym_pause_cap to advertise to the link partner that asymmetric pause is desired. For example, to prevent the device 'rge2' from advertising gigabit capabilities, enter (as super-user): # ndd -set /dev/rge2 adv_1000fdx_cap 0 All capabilities default to enabled. Note that changing any capability parameter causes the link to go down while the link partners renego- tiate the link speed/duplex using the newly changed capabilities. You can find the current parameter settings by using ndd -get. In addition, the driver exports the current state, speed, duplex setting, and working mode of the link via ndd parameters (these are read only and may not be changed). For example, to check link state of device rge0: # ndd -get /dev/rge0 link_status 1 # ndd -get /dev/rge0 link_speed 100 # ndd -get /dev/rge0 link_duplex 2 The output above indicates that the link is up and running at 100Mbps full-duplex. In addition, the driver exports its working mode by loop_mode. If it is set to 0, the loopback mode is disabled. FILES
