+- ``reclaim_mem_mode`` parameter [int]
+
+ Cache some resources in flow destroy will help flow recreation more efficient.
+ While some systems may require the all the resources can be reclaimed after
+ flow destroyed.
+ The parameter ``reclaim_mem_mode`` provides the option for user to configure
+ if the resource cache is needed or not.
+
+ There are three options to choose:
+
+ - 0. It means the flow resources will be cached as usual. The resources will
+ be cached, helpful with flow insertion rate.
+
+ - 1. It will only enable the DPDK PMD level resources reclaim.
+
+ - 2. Both DPDK PMD level and rdma-core low level will be configured as
+ reclaimed mode.
+
+ By default, the PMD will set this value to 0.
+
+- ``sys_mem_en`` parameter [int]
+
+ A non-zero value enables the PMD memory management allocating memory
+ from system by default, without explicit rte memory flag.
+
+ By default, the PMD will set this value to 0.
+
+- ``decap_en`` parameter [int]
+
+ Some devices do not support FCS (frame checksum) scattering for
+ tunnel-decapsulated packets.
+ If set to 0, this option forces the FCS feature and rejects tunnel
+ decapsulation in the flow engine for such devices.
+
+ By default, the PMD will set this value to 1.
