When pfring supports it, we open it with the PF_RING_LONG_HEADER option. However, I was told that when using "dna" mode, the 'long' header is not filled. Instead, we should "explicitly call the parsing routine calling pfring_parse_pkt()" in this case.

Question is: do we need the long header? If so, we need to fix the dna mode, otherwise, we need to remove the long hdr flag.
