udp_reflector is a tool to support the reflecting of udp traffic on a source
port to a mirrored destination port. Data is captured at the data link layer
using libpcap. This allows another process to bind to the port, and avoids
the error "Bind: Address Already in Use". udp_reflector supports both multiple
packet destinations and multiple ignore ports which are used to prevent the
infinite looping of packets between multiple udp_reflectors.
