* So, if that's the case, then we have the NMPlatformLnkTun instance

* falls back reading sysctl to obtain the tun properties. That
* is racy, because querying sysctl means that the object might
* be already removed from cache (while NM didn't yet process the
* netlink message).
*
* Hence, to lookup the tun properties, you always need to use this
* function, and use it with care knowing that it might obtain its
* data by reading sysctl. Note that we don't want to add this workaround
* to the platform cache itself, because the cache should (mainly)
* contain data from netlink. To access the sysctl side channel, the
* user needs to do explicitly.

*
* In most cases, NM_PLATFORM_IP_ROUTE_CMP_TYPE_ID comparison performs the same
* relaxed comparison. For example, normalize() will normalize "scope_inv", and also
* the NM_PLATFORM_IP_ROUTE_CMP_TYPE_ID comparison will do that on-the-fly. Optimally,
* looking into a hash table gives you the same result, whether you normalize the
* needle first (or whether the entries in the hash table are normalized).
*
* Unfortunately, that's not always the case. Examples:
*
* - "metric": we have a "metric_any" field. This is used by higher layers
* to indicate that the metric is dynamically chosen (e.g. by the default
* metric of the default route). As such, as far as NM_PLATFORM_IP_ROUTE_CMP_TYPE_ID
* is concerned, the "metric_any" and "metric" values are treated as distinguishing
* properties. But when we add a route in kernel, "metric_any" no longer exist.
* It becomes a fixed metric. Normalize will fix the metric.
* - "weight": for IPv4 single-hop routes, the weight does not exist in kernel. We however
* use the field to track ECMP information in higher layers. Consequently,
* NM_PLATFORM_IP_ROUTE_CMP_TYPE_ID treats the weight as-is, while normalization
* (and adding it to kernel) will mangle it.
*
* You thus must be careful when you track NMPlatformIP4Route that make use of such
* higher-level features, which cannot be represented in kernel or the NMPlatform
* cache.
