Functions

func ReuseportIsAvailable

func ReuseportIsAvailable() bool

ReuseportIsAvailable returns whether reuseport is available to be used. This is here because we want to be able to turn reuseport on and off selectively. For now we use an ENV variable, as this handles our pressing need:

DeP2P_TCP_REUSEPORT=false dep2p daemon

If this becomes a sought after feature, we could add this to the config. In the end, reuseport is a stop-gap.
