   8 commit 0cdefd5b5485ee6eb3512a75739d09a4090176ed upstream.
   9
  10 The CPU port of the BCM53125 is configured with RGMII (no delays) but
  11 this should actually be RGMII with transmit delay (rgmii-txid) because
  12 STMMAC takes care of inserting the transmitter delay. This fixes
  13 occasional packet loss encountered.

  15 Fixes: d7b9eaff5f0c ("ARM: dts: sun7i: Add BCM53125 switch nodes to the lamobo-r1 board")
