 HOOK_NIC_EVENT 9S "May 1, 2008"
 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
illumos DDI specific (illumos 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.
