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

hook_nic_event - data structure describing events related to network interfaces

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