The Create Port form is missing fixed ip input

[Dimitri Mazmanov]

When creating a port via CLI it is possible to specify the fixed ip argument:

Help text info for neutron help port-create:
  --fixed-ip subnet_id=SUBNET,ip_address=IP_ADDR
                        Desired IP and/or subnet for this port:
                        subnet_id=<name_or_id>,ip_address=<ip>. You can repeat
                        this option.

root@node1:~# neutron port-create N1 --fixed-ip ip_address=14.0.0.5

This input is missing from the Create Port form. Is it a bug or a new feature?
