RTE3 Use real time ethernet as "normal" ethernet interface
Well I tried the very same thing

64 bytes from icmp_seq=1 ttl=64 time=4.48 ms

but here as you can see every ping works.

Is there additional traffic running across this specific IP address or is it just the ping command as only message? What else are you running on your netPI? Other containers that could occupy the CPU a lot? What is the general traffice running over this network the cifx0 interface is connected to?

What is true is that the Ethernet LAN interface across netX chip (which was initially made for supporting industrial networks) is 10 times slower in communication and throughput than the standard eth0 interface. We have to pack all TCP/IP traffic into acyclic messages between Raspberry CPU and netX and as you know this interface is an SPI connection at 25Mhz clock rate only. But I doubt this is a root cause for loosing IP packets.
