Comment 6 for bug 1355341

I observe the issue on mainline #2010 and R1.1 #25 as well:

Steps :
1) Set the quota limit for subnet to 2 ( using UI)
2) From horizon ,create a n/w and add 2 subnets using the default IPAM.
3) Try to add 3rd subnet using the default IPAM,it gives error as expected.
4) Try to add a subnet again using a new created IPAM -- test-1 ,it allows to add 1 more subnet .
5) Try to add one more subnet using IPAM -test1 --it fails
6) Add one more subnet using new IPAM test-2 ,it allows
,So it allows 1 subnet addition per new IPAM created even though the quota limit set exceeded.
