Besides SW datapath stats, the kernel also support collecting statistics from HW datapath, for nexthop groups offloaded to HW. Request that these be collected when ip is given "-s -s", similarly to how "ip link" shows more statistics in that case. Besides the statistics themselves, also show whether the collection of HW statistics was in fact requested, and whether any driver actually implemented the request.
