Hi all,

I'm sorry for the late feedback.

I was wondering if we could use a new UDP-specific setsockopt to remove
the connected socket from the reuseport group at connect() time?

That would not have any behavioral change for existing application
leveraging the current reuseport implementation and requires possibly a
simpler implementation, but would need application changes for UDP
servers doing reuse/connect().

WDYT?

Cheers,

Paolo
