Working on this project and I keep seeing these overrun errors when doing throughput testing.
[ 5845.586176] mvneta d0040000.ethernet eth1: bad rx status 0fa30000 (overrun error), size=360
I did a google search and cannot see the issue.
The test conditions are as such I am running a traffic generator to this device (DUT) and then back so a loop from port 0 on traffic generator to port 0 on device and then out port 1 to port 1 on generator.
With this I can test symmetrical and asymmetrical throughput. Reliably I can get up to 1.25gbps through the device using UDP packets.
However once I get up to 1500 Byte packets start seeing those errors with as little as 16pps bidirectional traffic. The CPU of the DUT is not even getting hit it can handle that little of traffic but I still see the above errors.
What is causing that error or what can point me in the proper direction?
Details on the DUT it is simply a software bridge that takes packets from one interface and puts them to the other.
