Add the functionality for including address-family-specific per-link stats in RTM_GETSTATS messages. This is done through adding a new IFLA_STATS_AF_SPEC attribute under which address family attributes are nested and then the AF-specific attributes can be further nested. This follows the model of IFLA_AF_SPEC on RTM_*LINK messages and it has the advantage of presenting an easily extended hierarchy. The rtnl_af_ops structure is extended to provide AFs with the opportunity to fill and provide the size of their stats attributes. One alternative would have been to provide AFs with the ability to add attributes directly into the RTM_GETSTATS message without a nested hierarchy. I discounted this approach as it increases the rate at which the 32 attribute number space is used up and it makes implementation a little more tricky for stats dump resuming (at the moment the order in which attributes are added to the message has to match the numeric order of the attributes). Another alternative would have been to register per-AF RTM_GETSTATS handlers. I discounted this approach as I perceived a common use-case to be getting all the stats for an interface and this approach would necessitate multiple requests/dumps to retrieve them all.
