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
