Network Inventory Entries

Network Inventory Entries

When a device driver is initialized, it can install an entry in the system hardware inventory (see "Creating an Inventory Entry"). It is a good idea for a network driver to do this, because the netsnoop program relies on hardware inventory entries. After successfully initializing, a network device driver should call add_to_inventory() with the following five parameters (see sys/invent.h):

class INV_NETWORK
type The packet type, for example INV_NET_ETHER. See sys/invent.h for the possible "types for class network" list.
controller The kind of network controller from the "controllers for network types" list in sys/invent.h.
unit Any distinguishing number for this device. The hinv command does not decode this field.
state Any characteristic number for this device. The hinv command does not decode this field.
