Public bug reported:
Branch: master
When deleting a tenant router, the reference l3 agent performs the following
operations from within the qrouter namespace:
iptables-save
iptables-restore
ip6tables-save
find on /sys/class/net
find on /sys/class/net
iptables-save
ip6tables-save
find on /sys/class/net
Lastly, the qrouter namespace is removed, which begs the question of why
the above operations are performed - can they be optimized away?
