Types

type Config

type Config struct {
	// LinkEndpoints is the interface implemented by
	// data link layer protocols.
	LinkEndpoint stack.LinkEndpoint

	// TransportHandler is the handler used by internal
	// stack to set transport handlers.
	TransportHandler adapter.TransportHandler

	// MulticastGroups is used by internal stack to add
	// nic to given groups.
	MulticastGroups []net.IP

	// Options are supplement options to apply settings
	// for the internal stack.
	Options []option.Option
}

Config is the configuration to create *stack.Stack.
