NAME
     hook_nic_event - data structure describing events related to
     network interfaces

SYNOPSIS
     #include 
     #include 
     #include 


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 inter-
     face. 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  struc-
     ture.

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 struc-
                       ture that is hne_datalen  bytes  long  and
                       contains the new network address.


                   NE_IFINDEX_CHANGE

                       An interface index  has  changed.  hne_lif
                       refers  to the logical interface for which
                       the change is occurring, hne_data is a new
                       ifindex value.
