Description

I am able to successfully create an overlay network across multiple hosts.
However when u try to start any contains in that network i get the following error
Error response from daemon: 500 Internal Server Error: subnet sandbox join failed for "10.0.0.0/24": error creating vxlan interface: operation not supported.

Any help would be much appreciated.

Research direction

Use the reported Docker overlay-network startup path as the entry point, reproducing with Docker 1.10.3 on the listed ARM/Raspbian 4.4.9-v7+ environment. Compare the VXLAN failure against kernel support and determine whether a code change or an environment limitation is responsible; done means a confirmed cause and documented resolution.
