[dpdk-dev] [PATCH v7 0/5] examples/l3fwd: add FIB lookup method to l3fwd

[Conor Walsh <conor.walsh@intel.com>]

Currently the l3fwd sample app supports LPM and EM lookup methods this
patchset implements the FIB library as another lookup method for l3fwd.
Instead of adding an individual flag for FIB, a new flag '--lookup' has
been added that allows the user to select their desired lookup method.
The flags '-E' and '-L' have been retained for backwards compatibility.

---

v7:
    - Error log for invalid lookup method now runs within the parse_lookup
      function for better maintainability

v6:
    - rte_exit no longer used within parse_lookup, exiting due to
      incorrect config is now handled the same as the other config options
    - Corrected a typo within print usage
    - Moved -E and -L to the bottom of print usage as they are
      now legacy flags

v5:
    - Removed runtime checks to ensure desired port is within portmask,
      unused ports are still removed during setup

v4:
    - Changed individual switches for lookup methods to an
      enum for all lookup methods
    - Removed '-F' and introduced '--lookup' flag to select lookup methods
    - Fixed indentation issues
    - Renamed some variables for increased clarity
    - Minor changes to some logic for readability
    - Implemented MAC updating for FIB on non-SSE machines
    - Implemented RFC1812 for FIB on non-SSE machines
    - Added checks to ensure desired port is within portmask

v3: add support for NEON, PPC 64 and machines that do not support SSE,
    NEON or PPC 64.

v2: added the socket header file to fix FreeBSD build.
