Do you have any information about Intel 5300 CSI data structure?

Thanks for your contribution and providing a powerful toolkit to help me finish the first step of CSI learning. However, when my teammate and I wanted to do more future research on this topic, we found that if we could not figure out the data structure or the definition of the CSI frame, we could not go anywhere.

Here is our equipment information:

Wi-Fi adapter: Intel 5300
OS information: Ubuntu 16.04 with the kernel version 4.15
CSI-related toolset:

• https://github.com/spanev/linux-80211n-csitool
• https://github.com/dhalperi/linux-80211n-csitool-supplementary
• Gi-z/CSIKit

If you can provide me with any detail about the CSI data frame definition, I would appreciate what you did.
