/**
 * @file v1_cpi_add_route.h
 * @brief A hand-encoded CPI packet to add a route
 *
 * The v1 old-style control packet is a fixed header plus a tlv container 0xBEEF with a "value" of the CPI JSON string.
 * The packet type is 0xA4.
 *
 * This control packet has a CRC32C MIC on it.  Otherwise, same as v1_cpi_add_route.h
 *
 * Ground truth set derived from CRC RevEng http://reveng.sourceforge.net
 * e.g. reveng -c  -m CRC-32C 313233343536373839 gives the canonical check value 0xe306928e
 *
 * You can also calcaulate CRC32C online at http://www.zorc.breitbandkatze.de/crc.html using
 * CRC polynomial 0x1EDC6F41, init 0xFFFFFFFF, final 0xFFFFFFFF, reverse data bytes (check),
 * and reverse CRC result before final XOR (check).
 *
 * you can get the packet dump from the "write_packets" command.  here's the detailed steps.
 * The -c size of 4 in steps 4 and 7 are chosen to make it easy to delete the right number of lines.
 * there's nothing magic about the "4".
 *
 *  1) execute ./write_packets
 *  2) xxd -r -c 8 v1_cpi_add_route_crc32c.txt > y
 *  3) Delete the first 8 bytes and last 16 bytes and display has a hex string
 *       tail -c +9 y | head -c 158 | xxd -p -c 256
 *      The string should be "beef...077d7d7d"
 *  4) The string for this packet is too long for the website.  Use another tool such as reveng.
 *  5) The answer should be 78fd926a (the reveng answer will be byte reversed)
 *  6) Put the byte array from (5) in the Validation Payload.
