neutron port bindings extension not supported

[Rahul]

Port binding extension, specifically wrt to binding:host_id is desirable.

=============================================
 The binding Extended Attributes for Ports

List Ports
Show Port
Create Port
Update Port
Use the Networking API v2.0 with the binding extended attributes to get information about, create, and update port objects.

The binding-prefixed extended attributes for ports are:

Table 4.1. binding Extended Attributes for Ports
Attribute Type Required CRUD[a] Default Value Validation Constraints Notes
binding:vif_type

String

N/A

R

None

N/A

Read-only. The vif type for the specified port.

binding:host_id

uuid-str

N/A

CRU

None

N/A

The ID of the host where the port is allocated. In some cases different implementations can run on different hosts.

binding:profile

list(dict) N/A CRU None N/A
A dictionary that enables the application running on the specified host to pass and receive vif port-specific information to the plug-in.

binding:capabilities

list(dict) N/A R None N/A
Read-only. A dictionary that enables the application to pass information about functions that Networking API v2.0 provides. Specify the following value: port_filter : Boolean to define whether Networking API v2.0 provides port filtering features such as security group and anti-MAC/IP spoofing.

binding:vnic_type

String

N/A

CRU

normal

(normal, direct, macvtap)

The vnic type to be bound on the neutron port. To support SR-IOV PCI passthrough networking, you can request that the neutron port be realized as normal (virtual nic), direct (pci passthrough), or macvtap (virtual interface with a tap-like software interface). The ML2 plug-in supports the vnic_type.

[a]

C. Use the attribute in create operations.

R. This attribute is returned in response to show and list operations.

U. You can update the value of this attribute.

D. You can delete the value of this attribute.

There is no plan to support this in contrail. Needs further discussion before marking it 'won't fix'.

[Rahul (rahuls)]

Fixed with SR-IOV changes
