I'm hoping this will cut down on the confusion when reading the master branch's docs and seeing features not included in the latest stable Kops release..
A stopgap until we can properly version our documentation.
As per Lance Robson's message in Slack,
https://kubernetes.slack.com/archives/C3QUFP0QM/p1537959279000100?thread_ts=1537951563.000100&cid=C3QUFP0QM
above 50-100 nodes Calico recommends usage of BGP route reflectors:
> Clearly I'm not impartial here, but I can tell you that we test Calico to 5K
> nodes.
> We recommend BGP route reflectors once you go above ~50-100 nodes (we test up
> to 100 nodes without RRs). The reason for RRs is that by default calico sets up
> BGP connections in a full mesh - clearly the number of connections will scale as
> the number of nodes squared. With RRs, the number of BGP connections scales
> linearly with nodes - but then you have to manage the RRs too.
> The next version of Calico (v3.3 - code is in master already, but not heavily
> tested yet) will bring a feature to make RRs much easier to deploy - just
> annotate a few nodes and they become RRs.
Adding this detail to documentation as I recently got a cluster with such
issues.
fixes#2606
Most part of the changes are similar to current supported CNI networking
provider. Kube-router also support IPVS bassed service proxy which can
be used as replacement for kube-proxy. So the manifest for kube-router
included with this patch enables kube-router to provide pod-to-pod
networking, IPVS based service proxy and ingress pod firewall.
This gives the ability to a user to enable cross-subnet mode in Calico.
Also introduces a new addon that, full disclosure, I wrote.

* Integrating Canal (Flannel + Calico) for CNI
Initial steps to integrate Canal as a CNI provider for kops
Removed CNI in help as per chrislovecnm
* Integration tests, getting closer to working
- Added some integration tests for Canal
- Finding more places Canal needed to be added
- Sneaking in update to Calico Policy Controller
* Add updated conversion file
* turned back on canal integration tests
* fixed some rebase issues
* Fixed tests and flannel version
* Fixed canal yaml, and some rebasing errors
- Added some env vars to the install-cni container to get the proper
node name handed off
* Added resource limits
- set resource limits on containers for Canal
- Ran through basic calico tutorials to verify functionality
* Updating Calico parts to Calico 2.0.2
Adding the option to install Calico with the `--networking calico`
argument. This will currently deploy Calico v2.0 to the cluster.
Documentation has also been updated with information about Calico and
where one can find more information or help.
