- * INET         An implementation of the TCP/IP protocol suite for the LINUX
- *              operating system.  INET is implemented using the  BSD Socket
- *              interface as the means of communication with the user level.
- *
- *              IP/TCP/UDP checksumming routines

- *              Lots of code moved from tcp.c and ip.c; see those files
- *              for more names.
- *
- * 03/02/96     Jes Sorensen, Andreas Schwab, Roman Hodek:
- *              Fixed some nasty bugs, causing some horrible crashes.
- *              A: At some points, the sum (%0) was used as
- *              length-counter instead of the length counter
- *              (%1). Thanks to Roman Hodek for pointing this out.
- *              B: GCC seems to mess up if one uses too many
- *              data-registers to hold input values and one tries to
- *              specify d0 and d1 as scratch registers. Letting gcc
- *              choose these registers itself solves the problem.
