Hi

 

We have connected RGMII back to back between IMX and ZYNQ

Also we have taken care of PHY simulation in our driver.

The problem we are facing currently is while pinging "IMX <-> ZYNQ" with payload

we are seeing the packet loss.

This issue (PacketLoss) was not observed in freescale provided 3.0.35 kernel ,but is currenly observed

in 3.10.53 kernel

I have seen additional things like flow control has been added in 3.10.53 kernel

also there are few changes w.r.t  tx/rx flow .

Could that be resulting in packetloss issue
