Research direction
Start by locating the Raspberry Pi kernel configuration entry for CONFIG_NET_DROP_MONITOR and compare the current and next Raspberry Pi OS kernel configurations. Done means the option is enabled and the packaged dropwatch tool can run for packet-drop debugging without requiring a custom kernel.
Written by the indexing model from the issue text.
Description
Describe the bug
Since https://github.com/raspberrypi/linux/issues/6622 is probably not going to happen due to the massive size increase at least enabling the drop watch function within the kernel is sufficient to make the dropwatch tool work. It's still nowhere near as useful as being able to run pwru or retis to figure out where traffic gets mishandled, but it has no impact on the kernel size, and is still more convenient than having to rebuild a custom kernel just to be able to have a quick look.
Steps to reproduce the behaviour
try to run any of the mentioned tools to debug packet drops
Device (s)
Raspberry Pi CM5
System
current and next rpi os kernel
Logs
No response
Additional context
Dropwatch is available as a standard debian package, and is far less obscure than prwu and retis.
