Currently ovs is using device stats for Linux devices and count them itself in other situations. This leads to overlap with hardware stats, inconsistencies, etc. It's much better to just always count the packets flowing through the switch and let userspace do any merging that it wants. Following patch removes vport->get_stats() interface. vport-stat is changed to use new `struct ovs_vport_stat` rather than rtnl_link_stats64. Definitions of rtnl_link_stats64 is removed from OVS. dipf_port->stat is also removed as aggregate stats are only available at netdev layer.
