  - Support reading inline jumbo frame and dump them
    
    Add support for pkt_inline of jumbo frames.
    Dump the whole packet, and not a truncated packet. This might
    have a small impact on performance as the memory footprint
    is increased (by ~640K * number of tasks), resulting in potential
    higher DTLB misses.

  - Add support for multiple variables in core definition
    
    In the [core] definition we were able to use one variable
    such as $core1 in [core $core1] but not [core ${core1}].
    The second syntax is used when we want multiple
    variables such as in [core ${first_core}-${last_core}].
    This second syntax is now supported.
