LS1043A Packet Loss During Storming

[matt321]

Hi,

I'm using LS1043ARDB for a feasibility analysis on DPAA Driver. As part of that, we have did a packet storming with all the Ethernet interfaces enabled. Please find my observations and queries below,

Linux Kernel: 5.4 Yocto Build

1. We have observed packet loss, is it a limitation with the hardware or Linux kernel
2. Is this packet loss a known issue, and any solution in the upcoming releases?
3. We are following below setup while storming Screenshot from 2023-07-05 11-21-09.png

With this setup, we observed packet counts to certain Ethernet interfaces are not at all increasing. Packets are being sent to all interfaces. Is it a setup issue or expected behavior?

Thanks in advance,

Matt

// How do you enable the packet storming on fman ports?

For packets loss, As the setup, how do you observe the packet loss and how many packets had been lost?
Is there any steps to reproduce the issue?

Thanks.
