+description:
+  The Airoha AN8801R is a low power single-port Ethernet PHY Transceiver
+  with Single-port serdes interface for 1000Base-X/RGMII; this chip is
+  compliant with 10Base-T, 100Base-TX and 1000Base-T IEEE 802.3(u,ab)
+  and supports Energy Efficient Ethernet (802.3az), Full Duplex Control
+  Flow (802.3x), auto-negotiation, crossover detect and autocorrection,
+  Wake-on-LAN with Magic Packet, and Jumbo Frame up to 9 Kilobytes.
+  This PHY also supports up to three user-configurable LEDs, which are
+  usually used for LAN Activity, 100M, 1000M indication.
