Dear DPDK developers, In an attempt to integrate the Flow API into a third party application and allow the e.g., insertion/deletion of NIC classification rules from that application, I noticed that flow command parsing as per the most recent DPDK versions (i.e., 17.08 or 17.11) might benefit from some useful modifications.
Specifically, librte_cmdline provides libraries for parsing a flow command into tokens, but then the library for e.g., creating/deleting a flow rule for a DPDK NIC resides in test-pmd (app/test-pmd/cmdline_flow.c). My proposal is to move the app/test-pmd/cmdline_flow.c library into librte_cmdline, thus facilitate flow parsing for third party DPDK applications. I have a working prototype for both DPDK 17.08 and 17.11. This prototype extends librte_cmdline with 2 additional files (cmdline_flow.h and .c) and removes this functionality from test-pmd. The benefit is that the functions in cmdline_flow.h can now be re-used by any DPDK applications, which was not the case before. Do you think that the DPDK community will benefit from my patch? If so, I am happy to send you the patch for review and get your feedback to further improve it. In case I missed some other way to achieve my goal (without the need to patch DPDK), please let me know.
