Integration tests look to be constantly failing now.

I think the testCase in TestConfigureInterface is not correct.

I use Debian12 official iproute2 tools to input command as follow:
sudo ip addr add 10.20.30.40 dev eth0
sudo ip addr add 10.20.30.40 dev eth0

then i got:
RTNETLINK answers: File exists
apparently netlink doesn't allow add the same address to one dev multiple times.

Inside TestConfigureInterface(), the func ConfigureInterface(ifname string, netconf *NetConf)
calls rt.AddrAdd(iface, &addr.IPNet) with same addr and same iface. So, the last call expects
a error of 'file exits'.
