Joe Stringer 38c089d1d8 openvswitch: Fix dependency on IPv6 defrag.
When NF_CONNTRACK is built-in, NF_DEFRAG_IPV6 is a module, and
OPENVSWITCH is built-in, the following build error would occur:

net/built-in.o: In function `ovs_ct_execute':
(.text+0x10f587): undefined reference to `nf_ct_frag6_gather'

Fixes: 7f8a436eaa ("openvswitch: Add conntrack action")

Open vSwitch is a multilayer Ethernet switch targeted at virtualized
environments. In addition to supporting a variety of features
expected in a traditional hardware switch, it enables fine-grained
programmatic extension and flow-based control of the network. This
control is useful in a wide variety of applications but is
particularly important in multi-server virtualization deployments,
which are often characterized by highly dynamic endpoints and the
need to maintain logical abstractions for multiple tenants.
The Open vSwitch datapath provides an in-kernel fast path for packet
forwarding. It is complemented by a userspace daemon, ovs-vswitchd,
which is able to accept configuration from a variety of sources and
translate it into packet processing rules.
See http://openvswitch.org for more information and userspace
utilities.
To compile this code as a module, choose M here: the module will be
called openvswitch.
If unsure, say N.
