   tests: Add coverage for GSO/TSO and BIG TCP
   This commit adds coverage that affirms the current behavior of tcpdump
   when it parses packets captured in Linux with aggregation offloads
   enabled (such as GRO, GSO, TSO and BIG TCP).
   
   New tests include:
   
   1. GRO/GSO/TSO TCP packets. These have ip_len (IPv4) or payload_len
   (IPv6) set to a value bigger than MTU, but smaller than 64k (fits the
   width of the length field, which is 16 bits).
   
   2. BIG TCP packets, as currently implemented in Linux. These aggregated
   packets are larger than 64k. In IPv4, ip_len is just set to 0. In IPv6,
   payload_len is also set to 0, and the real length of the payload is
   indicated in the Jumbo option of the Hop-by-hop extension header,
   immediately following the IPv6 header.
   
   3. A corner case: a small (<64k) IPv4 packet with ip_len set to 0. Turns
   out that both tcpdump and wireshark treat such packets as valid,
   regardless of the transport protocol, simply printing a message that TSO
   was presumed. While my tests show that TSO actually fills in the correct
   (non-zero) value into the ip_len field, the test suite already contains
   a test called ipv4_tcp_http_xml_tso with a 2030-byte TCP/IPv4 packet
   that has ip_len = 0, but it's treated as a valid packet. The packet was
   captured in 2012, and the exact circumstances of why it has a zero
   ip_len are unclear to me, but if such packets are considered valid by
   both tcpdump and wireshark, I'm extending the coverage by adding an ICMP
   packet with ip_len = 0, which was manually crafted.

   ipv6: Support new BIG TCP without HBH
   Currently, BIG TCP IPv6 inserts a hop-by-hop extension header with a
   jumbo payload option to reflect the real length of the packet bigger
   than 65535 bytes. New kernels will drop this extension header and just
   calculate the packet length from skb->len, like it's currently done for
   BIG TCP IPv4.
   
   Reflect the future kernel change in tcpdump and support parsing such
   packets.
   
   BIG TCP only sets payload_len = 0 when the actual payload length is
   65536 or more. Check that explicitly, so that smaller packets with
   payload_len = 0 are still considered invalid, like in the test called
   icmpv6-length-zero. Check the transport protocol (next header) to be TCP
   or UDP because TCP may be inner in an encapsulated packet, e.g., in
   UDP-based tunnels, such as VXLAN and GENEVE.

   tests: Add coverage for new BIG TCP cases
   This commit adds tests for BIG TCP IPv6 without a hop-by-hop header, as
   announced in the previous commit, and also for encapsulated BIG TCP
   packets: TCP inside a VXLAN or GENEVE tunnel, for all combinations of
   outer/inner IPv4/IPv6.
   
   Besides that, this commit adds tests for similar tunneled packets, but
   non-BIG TCP, i.e. smaller than 64k, regular GSO. These packets don't set
   ip_len or payload_len to 0.
