17 .Nd IEEE 802.3 Media Independent Interface network bus
19 For most network interface cards (NIC):
24 driver provides an interconnection between the Media Access Control (MAC)
25 sublayer, the Physical Layer entities (PHY), Station Management (STA)
26 entities, and the PHY Layer as defined by the IEEE 802.3 Standard.
30 layer allows network device drivers to share common support
31 code for various external PHY devices.
32 Most 10/100 network interface cards either use an MII transceiver
33 or have built-in transceivers that can be programmed using an MII
37 driver currently handles all of the media detection,
38 selection, and reporting using the ifmedia interface.
39 A generic driver has been included for all PHYs that are not
40 handled by a specific driver, this is possible because all
41 10/100 PHYs implement the same general register set along with
42 their vendor specific register set.

101 The implementation of
103 was originally intended to have similar API interfaces
108 but as a result are not well behaved newbus device drivers.
