Propagate duplicate IF addr add/del error up to API.
Identify and complain when the same IP prefix is assigned to two different SW interfaces: vpp# set int ip address TenGigabitEthernet6/0/0 1.2.3.4/32 vpp# set int ip address TenGigabitEthernet6/0/1 1.2.3.4/32 set interface ip address: Prefix 1.2.3.4/32 already found on interface TenGigabitEthernet6/0/0 Change-Id: I1aee1b6a7ddd00d3109a53d8e1b6ce97bf45e372 Signed-off-by: Jon Loeliger <jdl@netgate.com>
