| Description: | |
| This attribute contains the PHY interface as configured by the | |
| Ethernet driver during bus enumeration, encoded in string. | |
| This interface mode is used to configure the Ethernet MAC with the | |
| appropriate mode for its data lines to the PHY hardware. | |
| Possible values are: | |
| <empty> (not available), mii, gmii, sgmii, tbi, rev-mii, | |
| rmii, rgmii, rgmii-id, rgmii-rxid, rgmii-txid, rtbi, smii | |
