We use the TLV flags as a handshake between the firmware and the driver. These flags allow the firmware to advertise its capabilities and API version. Since we are running short of bits, we add a new infrastructure which is more scalable, yet backward compatible. We make now the difference between API changes and the capabilities. Both can have an index which allows to scale at will. Signed-off-by: Eran Harary <eran.harary@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
