79 * Ethernet software status per device.
81 * Each interface is referenced by a network interface structure,
82 * ethercom.ec_if, which the routing code uses to locate the interface.
83 * This structure contains the output queue for the interface, its address, ...
85 * NOTE: this structure MUST be the first element in machine-dependent
86 * le_softc structures! This is designed SPECIFICALLY to make it possible
87 * to simply cast a "void *" to "struct le_softc *" or to
88 * "struct am7990_softc *". Among other things, this saves a lot of hair
89 * in the interrupt handlers.
