- * INET An implementation of the TCP/IP protocol suite for the LINUX

- * 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.
