It would be preferrable to disable UDP early demux for those systems
and enable it for TCP only.
Presumably you want this for performance reasons. Can you provide some
before and after numbers?
Hi Tom
We are working on UDPv6 performance issues seen on an Android ARM64
system.
Adding an early demux handler (link below) for it helped to increase
performance
(800Mbps -> 870Mbps). This helps because Android statistics rules do
multiple
socket lookup when no socket is associated with the skb.

Eric mentioned that server loads usually see more unconnected load and
he
preferred to turn off early demux for UDP, hence this patch. I don't
have numbers
for unconnected loads as of now though.
