    Support binding floating ip to smart-nic port
    
    When the Ironic use smart NICs to implement Bare Metal servers, the
    neutron L2 agent and L3 agent run locally on the smart NIC. The
    smart-nic port can be bound to the virtual bridge, and the floating
    ip can also be implemented by the L3 agent on the smart NIC.

Title:
  Support binding floating ip to smart-nic port in the dvr mode.

Status in neutron:
  Fix Released

Bug description:
  In DVR mode, neutron only allows binding flaoting IP to the normal
  port. When a floating IP is bound to a smart-nic port, neutron raise
  the error 'Port VNIC type is not valid to associate a FIP in DVR mode'
  [1]. When the Ironic use smart NICs to implement Bare Metal Servers,
  the port VNIC type is 'smart-nic', and the  Neutron L2 agent and L3
  agent run locally on the smart NIC. The smart-nic port can be bound to
  virtual bridge, and the floating IP can also be implemented by the L3
  agent on the smart NIC. So here [2] should also return ture when the
  port VINC type is 'smart-nic'.
