UDP in the kernel doesn't do that, and it doesn't tell userspace much either (you can try to detect packet drops in userspace, but coding that up is quite hard because the schdulers get in the way of measurement, and forget about ECN being seen in userspace)

Ahem.  man 7 ip :-  IP_RECVTOS
"If  enabled,  the  IP_TOS ancillary message is passed with incoming
packets.  It contains a byte which specifies the Type of
Service/Precedence field of the packet header."


I'll grant the rest of your rant.
