+Description: The main database in the Spectrum device is a centralized
+ KVD database used for many of the tables used to configure
+ the chip including L2 FDB, L3 LPM, ECMP and more. The KVD
+ is divided into two sections, the first is hash-based table
+ and the second is a linear access table. The division
+ between the linear and hash-based sections is static and
+ require reload before the changes take effect.
