Subject: Introduce a new toy interface, edsc(4).  It's a discard interface
 imitating an Ethernet device, so vlan(4) and if_bridge(4) can be attached to
 it for testing and benchmarking purposes.  Its source can be an introduction
 to the anatomy of a network interface driver due to its simplicity as well as
 to a bunch of comments in it.
