This PR add the option to configure an empty ipam for the macvlan cni plugin.
When using the macvlan cni plugin with an empty ipam the requeted pod will get the macvlan interface but without any ip address.
One of the use cases for this feature is for projects that runs a dhcp server inside the pod like KubeVirt.
In KubeVirt we need to let the vm running inside the pod to make the dhcp request so it will be able to make a release an renew request when needed.
We used to return error if no endpoint was found during delete. We now treat this as a success. If we fail during an add call, we now make a delete delegate call to the ipam to clean-up.
Now that libcni has the ability to print a version message, plumb it
through correctly.
While we're at it,
- fix import paths
- run gofmt
- add some more comments to sample
- add container runtime swappability for release
With the VLAN filter, the Linux bridge acts more like a real switch, Allow to tag and untag
vlan id's on every interface connected to the bridge.
This PR also creates a veth interface for the bridge vlan interface on L3 configuration.

Note: This feature was introduced in Linux kernel 3.8 and was added to RHEL in version 7.0.

Fix windows build
This adds the dns capability for supplying a runtime dnsConfig from a CRI. It also includes a bug fix for removing an endpoint when no IPAM is supplied. Adds version dependency of 0.3.0. Mild updates to windows READMEs.
Move the windows plugin to use the Host Compute (v2) APIs, as well
as clean-up the code. Allows win-bridge to use either the old API or Host Compute (v2) api
depending on a conf parameter. Fixes a leaked endpoint issue on windows for the v1 flow, and
removes the hns/pkg from the linux test run.
- Change variable name to camel style to fix golint warning
- Execute the IPAM to assign the IP address if it's inside in the config
- Test the IPAM module with static plugin
Recent CNI specification changes require the container ID on ADD/DEL,
which the testcases were not providing. Fix that up so things work
when this repo gets CNI revendored.
Namespace creation had an unergonomic interface and isn't used, except
for testing code. Remove it; downstream users should really be creating
their own namespaces
