Packet Loss in Ping Command

Question asked by himanshu gusain on Dec 4, 2015



We are observing packet loss while pinging with higher payload

using below command



"ping -s 1000 "


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
