Dumitrescu, Cristian Sept. 23, 2020, 6:06 p.m. UTC
Add VXLAN encapsulation example to the SWX pipeline application. The
VXLAN tunnels can be generated with the vxlan_table.py script. Example
command line: ./build/pipeline -l0-1 -- -s ./examples/vxlan.cli

+// frame.
+//
+// Assumption: When read from the table, the outer IPv4 and UDP headers contain
+// the following fields:
+//    - t.ipv4_total_len: Set to 50, which covers the length of:
+//         - The outer IPv4 header (20 bytes);
+//         - The outer UDP header (8 bytes);
+//         - The outer VXLAN header (8 bytes);
+//         - The inner Ethernet header (14 bytes);
+//    - t.ipv4_hdr_checksum: Includes the above total length.
+//    - t.udp_length: Set to 30, which covers the length of:
+//         - The outer UDP header (8 bytes);
+//         - The outer VXLAN header (8 bytes);
+//         - The inner Ethernet header (14 bytes);
+//    - t.udp_checksum: Set to 0.
+//
+// Once the total length of the inner IPv4 packet (h.ipv4.total_len) is known,
+// the outer IPv4 and UDP headers are updated as follows:
+//    - h.outer_ipv4.total_len = t.ipv4_total_len + h.ipv4.total_len
+//    - h.outer_ipv4.hdr_checksum = t.ipv4_hdr_checksum + h.ipv4.total_len
