Hi Harish,
    We do not use flow director at the moment. The code you refer to below was
for experimental purposes only and has been ifdef’ed out.

    Hi Raja,
    Thanks for the response.
    Is flow director a prerequisite to work with Contrail or is it a
    configurable option within Contrail to not to use it?
    From the code, it seems at-least for the MPLS case, Contrail makes use of
    flow director API rte_eth_dev_fdir_add_perfect_filter() to pass the MPLS
    label as the 'flex bytes' for filtering/Rx queue steering. If this is
    true, it creates a dependency on the NIC drivers to implement flow
    directors to be able to interop with Contrail solution.
    APIs like rte_eth_dev_fdir_add_perfect_filter() are deprecated in later
    DPDK releases. This means Contrail has to be adapted to use
    RTE_FDIR_MODE_PERFECT_TUNNEL flowdir mode (if flowdir is a must) or new
    filtering APIs like rte_eth_dev_filter_ctrl() with RTE_ETH_FILTER_TUNNEL
    mode (if flowdir is not required).
    Pls let me know.
