   4 Subject: [PATCH] arm64: dts: ls1028a-rdb: Enable SGMII AN for the QSGMII
   5  switch ports
   6
   7 This enables monitoring of link status and AN. It should also physically
   8 enable SGMII AN with the VSC8514 PHY, but in practice that is still
   9 hardcoded as "on" in the PHY driver, at the moment. So since Felix
  10 actually disables SGMII AN when this DT property is absent, this would
  11 result in an in-band AN mismatch between the MAC and the PHY. So this
  12 property is required for the moment for this MAC/PHY combination.
