// Enable spoofing if a stack may send packets from unowned addresses.
// This change required changes to some netgophers since previously,
// promiscuous mode was enough to let the netstack respond to all
// incoming packets regardless of the packet's destination address. Now
// that a stack.Route is not held for each incoming packet, finding a route
// may fail with local addresses we don't own but accepted packets for
// while in promiscuous mode. Since we also want to be able to send from
// any address (in response the received promiscuous mode packets), we need
// to enable spoofing.
