hook_nic_event(9S)					    Data Structures for Drivers 					hook_nic_event(9S)

NAME

       hook_nic_event - data structure describing events related to network interfaces

SYNOPSIS

       #include <sys/neti.h>
       #include <sys/hook.h>
       #include <sys/hook_event.h>

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

DESCRIPTION

       The  hook_nic_event  structure contains fields that relate to an event that has occurred and belongs to a network interface. This structure
       is passed through to callbacks for NE_PLUMB, NE_UNPLUMB, NE_UP, NE_DOWN and NE_ADDRESS_CHANGE events.

       A callback may not alter any of the fields in this structure.

STRUCTURE MEMBERS

	 net_data_t	      hne_family;
	 phy_if_t	      pkt_private;
	 lif_if_t	      hne_lif;
	 nic_event_t	      hne_event;
	 nic_event_data_t     hne_data;
	 size_t 	      hne_datalen;

       The following fields are set for each event:

       hne_family    A valid reference for the network protocol that owns this network interface and can be in calls to  other	netinfo(9F)  func-
		     tions.

       hne_nic	     The physical interface to which an event belongs.

       hne_event     A value that indicates the respective event. The current list of available events is:

		     NE_PLUMB		  an interface has just been created.

		     NE_UNPLUMB 	  an interface has just been destroyed and no more events should be received for it.

		     NE_UP		  an interface has changed the state to "up" and may now generate packet events.

		     NE_DOWN		  an interface has changed the state to "down" and will no longer generate packet events.

		     NE_ADDRESS_CHANGE	  an  address on an interface has changed. hne_lif refers to the logical interface for which the change is
					  occurring, hne_data is a pointer to a sockaddr structure that is hne_datalen bytes long and contains the
					  new network address.

NAME

       net_getlifaddr - determine a network address for a given interface

SYNOPSIS

       #include <sys/neti.h>

       int net_getlifaddr(const net_data_t net, const phy_if_t ifp,
	    const net_if_t lif, int const type,
	    struct sockaddr* storage);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

       net	  value returned from a successful call to net_protocol_lookup(9F).

       ifp	  value  returned from a successful call to net_phylookup(9F) or net_phygetnext(9F), indicating which network interface the infor-
		  mation should be returned from.

       lif	  indicates the logical interface from which to fetch the address.

       type	  indicates what type of address should be returned. See below for more details on this field.

       storage	  pointer to an area of memory to store the address data.

DESCRIPTION

       The net_getlifaddr() function retrieves the address information for each logical interface. Each call to net_getlifaddr() requires that the
       caller  pass  a pointer to an array of address information types to retrieve, and an accompanying pointer to an array of pointers to struct
       sockaddr structures to which to copy the address information. See net_lifgetnext(9F) for an example on how to use this function.

       Each member of the address type array should be one of the values listed here.

       NA_ADDRESS      Return the network address associated with the logical interface (lif) that belongs to the network interface (ifp).

       NA_PEER	       Return the address assigned to the remote host for point to point network interfaces for the given  network/logical  inter-
		       face.

       NA_BROADCAST    Return  the broadcast address assigned to the given network/logical interface for network interfaces that support broadcast
		       packets.

       NA_NETMASK      Return the netmask associated with the given network/logical interface for network interfaces that support broadcast  pack-
		       ets.

RETURN VALUES

       The net_getlifaddr() function returns:

       -1    The network protocol does not support this function.

       0     Successful completion.

       1     Unsuccessful.

CONTEXT

       The net_getifaddr() function may be called from user, kernel, or interrupt context.
