Quoting Andrew Gallatin <gallatin@cs.duke.edu> (Thu, 25 May 2006 12:20:17 -0400 (EDT)): > If we're going to do anything, I'd prefer to see us skip > the checksum on everything sent across lo0 and stick with > the slower, yet known to work, existing checksum code for > slow interfaces. The current code is known to work with the current gcc we use. It is known to *not* work with the Intel C compiler. It may or may not work with an upcomming gcc version. The current code is a maze of assembly and macros, the new one is straight forward C and a little bit of assembly. And the new one is also known to work in DragonFlyBSD. Do you expect *this* code to act differently between FreeBSD and DragonFlyBSD? What's the technical backing of your preference to stick with the current code? How does the technical backing of your preference compare to the technical arguments I presented in this thread regarding the priority of the arguments?
