description: |
  The DAP8211R(I) is a Gigabit Ethernet PHY with RGMII interface,
  supporting IEEE 802.3az Energy Efficient Ethernet, IEEE 1588 SyncE,
  and an internal packet generator for diagnostics.

  Specifications:
    - 10BASE-Te, 100BASE-TX, 1000BASE-T
    - RGMII with configurable TX/RX clock delays (150 ps steps, 0-2250 ps)
    - IEEE 802.3az-2010 Energy Efficient Ethernet
    - IEEE 1588 SyncE support
    - Internal packet generator and checker for link diagnostics
