Hi,

The kernel supports Open vSwitch and VXLAN tunnels, as seen in the kernel_config (CONFIG_OPENVSWITCH and CONFIG_OPENVSWITCH_VXLAN).

Unfortunately, it doesn't support GRE tunnels.
It would be great to add it, by adding CONFIG_OPENVSWITCH_GRE to the kernel_config.

Thanks (and btw, thanks for boot2docker 👍!!)
