Hi

We are observing packet loss while pinging with higher payload

using below command

Command

"ping -s 1000 192.19.253.11 "

Result

6 packets transmitted, 1 received, 83% packet loss, time 5006ms

When we check in /sys/class/net/eth0/statistics

rx_bytes               : 677519

rx_compressed    : 0

rx_crc_errors       : 0

rx_dropped          : 0

rx_errors              : 0

rx_fifo_errors       : 0

rx_frame_errors   : 0

rx_length_errors   : 0

rx_missed_errors  : 0

rx_over_errors      : 0

rx_packets            : 5350

Here it doesn't shows any packet error or dropped

Not only this ,We have observed the packet loss sometime without payload as well

What is the best way to debug this problem

Driver we are using : drivers/net/ethernet/freescale/fec_main.c

Kernel version: 3.10.53

OS : Android Lollipop

Note: We have connected Free-scale board with Zynq (Mac-to-Mac), and also taken care of PHY values in our drivers

                    

Already we have posted lot of queries in the forum related to this ,but didn't received much response

Our project is in critical stage ,Could it be possible to through up some point which can  be used resolve this

issue

Regards

Himanshu
