Bug 8471 - Traffic between a VM without FIP and a VM with FIP is not
working

1)Hairpinning changes are done for conntrack based SNAT, now it matches
on external subnet id that external n/w id.
2) The packets are submitted back to table 21 from 47.
3)L3_GW_MAC_TABLE (Table 19)  replace the external n/w id with external
subnet id for the packet address to router external interface
4)L3_FIB_TABLE (Table21) flow now matched external subnet id  instead of
n/w is along with external ip address.
