BOXER-8250AI Series

Dear Aaeon,

On BOXER-8250AI Jetpack 5.0.x or Jetson Linux 34.X/35.X under kernel 5.10.104-tegra using igb driver the ping can go from 50-1000ms. However, on Jetpack 4.6.2 Jetson Linux 32.7/32.6 Linux kernel 4.9.253-tegra, we can get reliable ~0.5 ms ping.

The problem is similar to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=939200

I know Jetpack 5.0.x is not supported. But I report this issue to get some feedback on the future direction. Do we patch the kernel or there will be a hardware revision in the future (according to our testing Jetpack 5.0.x work fine in BOXER-8253AI-A1-1011 using igb version: 5.10.104-tegra)?
