The +.Nm +layer allows network device drivers to share support code for +various PHY models, and allows unused support for PHYs which +are not present in a system to be removed from the kernel. +.Pp +Network device drivers which use the +.Nm +layer carry the +.Dq mii +autoconfiguration attribute. This allows kernel configuration +files to simply specify PHYs as described above in the synopsis. +.Pp +The following is an example of the messages displayed when a network +interface with an attached PHY is detected by the kernel: +.Bd -literal -offset indent +epic0 at pci0 dev 12 function 0: SMC EPIC/100 Fast Ethernet +epic0: interrupting at kn20aa irq 4 +epic0: SMC9432TX, Ethernet address 00:e0:29:07:17:c4 +qsphy0 at epic0 phy 3: QS6612 10/100 media interface, rev. 1 +qsphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto +.Ed +.Pp +All PHY drivers display the media types supported by the PHY when it +is detected by the kernel.
