Why are symmetric hashes required?

Because they want load balancing, such that one flow only can overrun
one single socket not all of the ones in the fanout.

I'm still missing it. Why is this any different than what we need with
something like SO_REUSEPORT?

Every single user of AF_PACKET fanout wants this behavior.
