NAME

       vni - STREAMS virtual network interface driver

DESCRIPTION

       The  vni  pseudo  device  is  a	multi-threaded, loadable, clonable, STREAMS pseudo-device supporting the connectionless Data Link Provider
       Interface dlpi(7P) Style 2. Note that DLPI is intended to interact with IP, meaning that DLPI access to applications is not supported. (For
       example, snoop fails on the vni interface.)

       The  vni  device is a software-only interface and does not send or receive data. The device provides a DLPI upper interface that identifies
       itself to IP with a private media type. It can be configured via ifconfig(1M) and can have IP addresses assigned to it, making aliases pos-
       sible.

       The  vni  pseudo  device  is  particularly  useful in hosting an IP address when used in conjunction with the 'usesrc' ifconfig option (see
       ifconfig(1M) for examples).  The logical instances of the device can also be used to host addresses as an alternative to hosting them  over
       the loopback interface.

       Multicast  is not supported on this device. More specifically, the following options return an error when used with an address specified on
       vni: IP_MULTICAST_IF, IP_ADD_MEMBERSHIP, IP_DROP_MEMBERSHIP, IPV6_MULTICAST_IF, IPV6_JOIN_GROUP, IPV6_LEAVE_GROUP. In  addition,  broadcast
       is not supported.

       Because	there  is no physical hardware configured below it, no traffic can be received through nor transmitted on a virtual interface. All
       packet transmission and reception is accomplished with existing physical interfaces and tunnels. Because applications that deal with packet
       transmission  and  reception  (such  as packet filters) cannot filter traffic on virtual interfaces, you cannot set up a packet filter on a
       virtual interface. Instead, you should configure the policy rules to apply to the physical interfaces and tunnels, and  if  necessary,  use
       the virtual IP addresses themselves as part of the rule configuration. Also, note that the virtual interface cannot be part of an IP multi-
       pathing (IPMP) group.

NAME

       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).
