    This patch adds support for the IFLA_STATS_LINK_XSTATS_SLAVE attribute
    which allows to export per-slave statistics if the master device supports
    the linkxstats callback. The attribute is passed down to the linkxstats
    callback and it is up to the callback user to use it (an example has been
    added to the only current user - the bridge). This allows us to query only
    specific slaves of master devices like bridge ports and export only what
    we're interested in instead of having to dump all ports and searching only
    for a single one. This will be used to export per-port IGMP/MLD stats and
    also per-port vlan stats in the future, possibly other statistics as well.
