This RFC intends to provide a way to dump all the offloaded rte flows in HW. This is very helpful for user and developer to debug flow offloading stuff, i.e, to check whether PMD offloads the rte flow in a correct way from HW perspective.
A private PMD API is provided as well as a socket server for external tool to trigger dump. The output file is in raw format and Mellanox specific. An external vendor (Mellanox) provided tool is needed in order to get human readable format. Please be aware the underlying rdma-core lib also needs to support this.
