VAT and CLI use different byte orders when adding and reading interface IP addresses.

Test:
Start VPP
~/Projects/vpp/build-root$ telnet 0 5002
vpp# set interface ip address local0 1.2.3.4/24
vpp# show int address
GigabitEthernet0/8/0 (dn):
local0 (dn):
1.2.3.4/24
pg/stream-0 (dn):
pg/stream-1 (dn):
pg/stream-2 (dn):
pg/stream-3 (dn):

Now reading with VAT:
~/Projects/$ sudo vpp_api_test json
vat# ip_address_dump ipv4 sw_if_index 0

[

{ "ip": "4.3.2.1", "prefix_length": 24 }

]

So VAT and CLI treat the bytes differently. Which one is correct ?
