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