	  Bluetooth stack via L2CAP channel.

	  This workaround is necessary to interoperate with Linux up to 4.10 but
	  it might not be compliant with RFC 7668 as it cause the stack to skip
	  Neighbor Discovery cache causing the destination link address to be
	  omitted. For more details why this is needed see:
