[Buildroot] Weird ping behaviour

[rob.r374 at gmail.com <rob.r374@gmail.com>]

Hello,

 

I'm following this buildroot build and get quite strange behaviour on
ethernet network.

Ping response times vary quite a lot and then ping crashes at the end.

 

Is there any setting, compile option that would help in this case ?

 

Thanks,

Regards,

Rob.
