I am trying to send ping packets from windows 7 to imx6. These ping packets have a size over 8000 bytes. Windows and imx6 have 1500 MTU. Under 8000 bytes there is no problem. But over 8000, I see fifo overrun statistics increasing. I saw at nxp forums this ERRATA: ERR004512. Is my stuation related with this ? Because when I put some delay at transmit side(windows 7 or another linux), there is no problem sending over 8k.
