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.
