trafgen: Dump proto headers in *.cfg format
Added trafgen_dump.c module which dumps headers from packet in .cfg format. Packet is dumped if -o <file>.cfg was specified, it might be useful to specify *.pcap file as input and convert it into .cfg file to edit proto fields in human readable format. To make it possible several main changes were added: 1) packet id is embedded into struct packet.id, and it is updated on each realloc_packet() 2) Added new struct proto_hdr.get_next_proto callback to make possible apply fields of next header. 3) Added new dev_io ops for writting packets into .cfg file, to re-use common dev_io mechsnism for packets dumping. Before dump the default ETH_PROTO fields are applied as first header and then next proto_hdr is identified via .get_next_proto(...) callback. Meanwhile only eth, arp, vlan, ip4, udp, & tcp protos can be dissected into *.cfg format. Signed-off-by: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
