printer.

* computing the negative of that value.
*
* "sum" is the value of the checksum field, and "computed_sum"
* is the negative of the sum of all the data in the packets,
* so that's -(-computed_sum - sum), or (sum + computed_sum).
*
* All the arithmetic in question is one's complement, so the
* addition must include an end-around carry; we do this by
* doing the arithmetic in 32 bits (with no sign-extension),
* and then adding the upper 16 bits of the sum, which contain
* the carry, to the lower 16 bits of the sum, and then do it
* again in case *that* sum produced a carry.
*
* As RFC 1071 notes, the checksum can be computed without
* byte-swapping the 16-bit words; summing 16-bit words
* on a big-endian machine gives a big-endian checksum, which
* can be directly stuffed into the big-endian checksum fields
* in protocol headers, and summing words on a little-endian
* machine gives a little-endian checksum, which must be
* byte-swapped before being stuffed into a big-endian checksum
* field.
*
* "computed_sum" is a network-byte-order value, so we must put
* it in host byte order before subtracting it from the
* host-byte-order value from the header; the adjusted checksum
* will be in host byte order, which is what we'll return.

* However, draft-hsmit-isis-aal5mux-00.txt describes a

*
* 1) the first byte of an IP header is 0x45-0x4f

*
* 2) the first byte of an OSI CLNP packet is 0x81,
* the first byte of an OSI ES-IS packet is 0x82,
* and the first byte of an OSI IS-IS packet is
* 0x83;
*
* so the network layer protocol can be inferred from the
