The buffer pool table contains buffer pool configuration and operational information. Each entry corresponds to a buffer pool. The Entry ID value represents the buffer pool ID to access.
The buffer pool table is a static bounded index table, buffer pools are always present and enabled. It only supports Update and Query operations, This patch only adds ntmp_bpt_update_entry() helper to support updating the specified entry of the buffer pool table. Query action to the table will be added in the future.
