If have just booted into 2.6.0-test4. Unplugging works, but the
console is flooded with:
last-F IN=br0 OUT=br0 PHYSIN=eth1 PHYSOUT=eth0 SRC=10.96.96.25 DST=10.96.96.255
[last-F ist the last rule in my FORWARDING iptable and does log+drop]
Obviously I must allow forwarding br0 <=> br0.
While I am writing this the counter on the FORWARDING rule -i br0 -o
br0 -j ACCEPT has reaches 2000+ packets with eth0 unplugged and the
kernel ist still running.
In both 2.4.22 and 2.6.0-test4 all of netfilter and advanced routing
ist set to M. In 2.6.0-test4 this includes ebtables.
Hope that helps
Hannes
