Drop packet(reason: Layer 2 packet forwarded in hardware(PP)) cause HIGH CPU

About every 10mins the CPU on two different MLX 16 LP cards will be at 50% for about 10 mins. Here is a sample of the debug capture.

[ Edited ]

We are seeing the same issue. Did you get an answer as to why this happens.

We are running IronWare : Version 5.4.0dT163
