I assume you mean that you're trying to use the upstream kernel module. If so,
that won't work. From our recently added FAQ:

Q: What features are not available in the Open vSwitch kernel datapath
that ships as part of the upstream Linux kernel?
A: The kernel module in upstream Linux 3.3 and later does not include
the following features:
- Bridge compatibility, that is, support for the ovs-brcompatd
daemon that (if you enable it) lets "brctl" and other Linux
bridge tools transparently work with Open vSwitch instead.
We do not expect bridge compatibility to ever be available in
upstream Linux. If you need bridge compatibility, use the
kernel module from the Open vSwitch distribution instead of the
upstream Linux kernel module.
- Tunnel and patch virtual ports, that is, interfaces with type
"gre", "ipsec_gre", "capwap", or "patch". It is possible to
create tunnels in Linux and attach them to Open vSwitch as
system devices. However, they cannot be dynamically created
through the OVSDB protocol or set the tunnel ids as a flow
action.
Work is in progress in adding these features to the upstream
Linux version of the Open vSwitch kernel module. For now, if
you need these features, use the kernel module from the Open
vSwitch distribution instead of the upstream Linux kernel
module.
