Thanks, - Greg
Ok, I will do that. Thanks for reviewing.

On 4.14 kernels, if kernel isn't configured with CONFIG_NF_CONNTRACK_IPV4 and CONFIG_NF_CONNTRACK_IPV6, openvswitch module will fail to load. The error message is "openvswitch: failed to init nf_conncount -91". This patch prints helpful error message for this case.
