If anyone has any objections, please let me know. ------------------ From: Lorenz Bauer [ Upstream commit ce796e60b3b196b61fcc565df195443cbb846ef0 ] Rename the existing reuseport helpers for IPv4 and IPv6 so that they can be invoked in the follow up commit. Export them so that building DCCP and IPv6 as a module works. No change in functionality.
