36 .Nd Ethernet discard network interface
42 interface is a software discard mechanism which may be
43 used for performance analysis and software testing.
44 It imitates an Ethernet device, which
45 allows for its use in conjunction with such drivers as
50 As with other network interfaces, an
52 interface must have network addresses assigned for each address family
53 with which it is to be used.
54 These addresses may be set or changed with the
