hook_nic_event - data structure describing events related to network interfaces
#include <sys/neti.h>

illumos DDI specific (illumos DDI).
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.
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.
