// TODO(https://fxbug.dev/42076420): Must be kept in sync with netstack's Inspect
// tree manually in lieu of automated testing solution.

// TODO(https://fxbug.dev/372466789): The tags here are prefixed with
// `netstack-` to avoid conflicts with netstack2's persistence config. Once
// netstack2 is deleted, we can remove these prefixes as they're a bit
// redundant.
