SubjectRe: ICMP redirect ignored

I had a sysctl patch I sent to Linus and Alan a while back, but it's
not really pre-2.0 critical. I'll probably rework it for 2.1, but the
gist of it was:

# cat /proc/sys/net/ipv4/ip_forward
# echo "0" > /proc/sys/net/ipv4/ip_forward

And then IP forwarding was off.
(Of course, I forgot to reflect the change in the SNMP and ICMP
redirect code, but that's why I'm reworking it....might also be why
Linus was ignoring it. =) )

Same deal with the ARP tuning stuff.
