The memlat protocol is intended for the management of memlat based scaling for devices like l3. The commands in this protocol provide functionality to configure memlat details, which includes memgrps, memlat monitors, memlat tunables, configuring the log levels and debugging support. Add a header file to define the memlat_vendor_ops structure to support modularization of this protocol.
