NAME

6       ntxn - NetXen 10/1 Gigabit Ethernet network driver
7

SYNOPSIS

9       /dev/ntxn*
10
11

DESCRIPTION

13       The  ntxn  10/1  Gigabit Ethernet driver is a multi-threaded, loadable,
14       clonable, GLD-based STREAMS driver supporting the  Data  Link  Provider
15       Interface, dlpi(7P), on NetXen 10/1 Gigabit Ethernet controllers.
16
17
18       The  ntxn driver functions include chip initialization, frames transmit
19       and receive, promiscuous and multicast support, TCP  and  UDP  checksum
20       off-load (IPv4) and 9600 bytes jumbo frame.
21
22
23       The  ntxn  driver  and  hardware support the 10GBASE CX4, 10GBASE-SR/W,
24       LR/W, and 10/100/1000BASE-T physical layers.
25

APPLICATION PROGRAMMING INTERFACE

27       The cloning character-special device, /dev/ntxn, is used to access  all
28       NetXen devices installed within the system.
29
30
31       The ntxn driver is managed by the dladm(1M) command line utility, which
32       allows VLANs to be defined on  top  of  ntxn  instances  and  for  ntxn
33       instances to be aggregated. See dladm(1M) for more details.
34
35
36       The  values  returned  by  the  driver  in the DL_INFO_ACK primitive in
37       response to your DL_INFO_REQ are:
38
39           o      Maximum SDU is 9600.
40
41           o      Minimum SDU is 0.
42
43           o      DLSAP address length is 8.
44
45           o      MAC type is DL_ETHER.
46
47           o      SAP (Service Access Point) length value is -2,  meaning  the
48                  physical  address  component  is  followed  immediately by a
49                  2-byte SAP component within the DLSAP address.
50
51           o      Broadcast  address  value  is  the  Ethernet/IEEE  broadcast
52                  address (FF:FF:FF:FF:FF:FF).
53

CONFIGURATION

55       By default, the ntxn driver works without any configuration file.
