ZYNQ ethernet phy using KSZ9031RN of problem

Hi xilinx members:

 

 

I had problem when ZYNQ use KSZ9031RN perform "ping" large transfer(>512 byte) to PC which occured packet loss.

 

But, PC performing large transfer (>1024 byte) "ping" to ZYNQ which it's right.

 

Checked the ZYNQ -> PHY of TX_CTL width time no changed at each transfer.

 

I want to know, it's ZYNQ MAC problem or KSZ9031RN?

 

Thank you!
