Does there exist any available PMTU code for 4.4 or 4.3 kernels that
would fit in?
Alternatively, is there something reasonably available, that might
boot from a floppy that does it? Something with telnet or something on
the floppy? My test packet generation equipment is all NetBSD/i386,
and I need to test some DF bit handling code. I guess I could take a
look for a suitable Linux boot image..
One question: wouldn't the host routes get allocated by the TCP
code, and referenced in their route cache pointer?
