set CONFIG_NET_DROP_MONITOR=y

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.
