SO_REUSEPORT does not exist on Linux but the checks are available in the code. With a little patch, it's possible to implement the feature, but the value of SO_REUSEPORT will still have to be known from userland. This patch adds a workaround to this problem by figuring out the value for the one used by SO_REUSEADDR.
