IPV6_V6ONLY support for the setsockopt part has been added a while ago, but it looks like the get part got forgotten. It should have been present as a way to verify a setting has been set as expected, and not to act differently from TCP or any other socket types. Not supporting this getsockopt(IPV6_V6ONLY) blocks some apps which want to check the default value, before doing extra actions. On Linux, the default value is 0, but this can be changed with the net.ipv6.bindv6only sysctl knob. On Windows, it is set to 1 by default. So supporting the get part, like for all other socket options, is important. Everything was in place to expose it, just the last step was missing. Only new code is added to cover this specific getsockopt(), that seems safe.

If the ov08x40_identify_module() call is skipped on probe() it should be done on the first stream start. Add the missing call. Note ov08x40_identify_module() will only do something on its first call, subsequent calls are no-ops.
