To be compatible with previous kernel versions we fall back on previous predefined values, same as the emulation values, when the ioctl is found to not support capability chains. If individual CLP capabilities are not found, we fall back on default values for only those capabilities missing from the chain. This patch is based on work previously done by Pierre Morel.
