LS1012AFRWY SGMII Packet loss

Hi.

   I use a network cable to connect the SGMII ports of two ls1012afrwy directly, and the ping test will drop packets.However, ls1012afrwy's SGMII is connected to other devices without problems.

   Also using two ls1012ardb to test SGMII is no problem.

   The phy chip used by the LS1012AFRWY is ar8033. Is there any problem with the LS1012A?

   I use ethtool to check the status of the NIC and found IEEE_rx_drop: 10
