Description of problem:
The system loosing an ipv6 address/route distributed via autoconf
after the lifetime. this worked with fedora core 2.
Interestingly when I start tcpdump, I see the Router Advertisements,
and the it starts working. Not using tcpdump once => not working.
I suppose this has something to do with the acceping/receiving of
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot the box
2. IPv6 address there
3. Wait for the address lifetime
4. address gone
Expected Results: The Lifetime timers should be updated every time a
new RA is received
It seem to be cured by setting the device into promiscous mode for a
sufficently long period of time (longer than the ra-interval is enough):
ifconfig $DEVICE promisc && sleep $INT && ifconfig $DEVICE -promisc
