Create a new template table with larger flows capacity.\n2. Re-create existing flows in the new table and delete flows from\n the original table.\n3. Destroy original table.\n\nApplication cannot always execute that procedure:\n* Port may not have sufficient resources to allocate a new table\n while maintaining original table.\n* Application may not have existing flows \"recipes\" to re-create\n flows in a new table.\n\nThe patch defines a new API that allows application to resize\nexisting template table:\n\n* Resizable template table must be created with the\nRTE_FLOW_TABLE_SPECIALIZE_RESIZABLE_TABLE bit set.\n\n* Application resizes existing table with the\n `rte_flow_template_table_resize()` function call.\n The table resize procedure updates the table maximal flow number\n only. Other table attributes are not affected by the table resize.\n ** The table resize procedure must not interrupt\n existing table flows operations in hardware.\n ** The table resize procedure must not alter flow handlers held by\n application.\n\n* After `rte_flow_template_table_resize()` returned, application must\n update all existing table flow rules by calling\n `rte_flow_async_update_resized()`.\n The table resize procedure does not change application flow handler.\n However, flow object can reference internal PMD resources that are\n obsolete after table resize.\n `rte_flow_async_update_resized()` moves internal flow references\n to the updated table resources.\n The flow update must not interrupt hardware flow operations.\n\n* When all table flow were updated, application must call\n `rte_flow_template_table_resize_complete()`.\n The function releases PMD resources related to the original\n table.\n Application can start new table resize after\n `rte_flow_template_table_resize_complete()` returned.\n\nTestpmd commands:\n\n* Create resizable template table\nflow template_table <port-id> create table_id <tbl-id> resizable \\\n
