How IMX6D implements interrupt load balancing

Hello everyone, my Linux version is 3.14.52 and my development board is MCIMX6Q-SDB. During the development process, I found that many interrupts are concentrated on CPU0. This has caused the problem of packet loss during Gigabit transmission. What should I do to make it interrupt load balancing.

Hi, I checked the link you provided. However, it does not mention how to solve the problem of interrupted load balancing.What I want to know is whether IMX6 supports interrupt load balancing in Linux 3.14.52.If supported, how do I need to achieve it
