Summary: This small patch makes socket buffer timestamps 1 usec accurate
(could be down to 10 nsec btw.), with no ISA cycle overhead. Useful for
tcpdump packet ordering. Only on Pentiums :(
Warning: ALPHA software. And it's so dirty that if this goes into the
kernel i shoot Linus myself 8)
if you still want to try it:
i patched two files:
arch/i386/kernel/timer.c
net/core/dev.c
The "diff -u" patch files are MIME attached. "cd" to arch/i386/kernel and
net/core to apply the patches, they contain no path.
good luck, please tell me if it doesnt work for you. (works for me with
zero problems). (tell me if you dont like it or if it's useless)
