 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) functions.





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.
