hns_get_sset_count() returns HNS_NET_STATS_CNT and the data space allocated is not enough for ethtool_get_strings(), which will cause random memory corruption. When SLAB and DEBUG_SLAB are both enabled, memory corruptions like the the following can be observed without this patch: [ 43.115200] Slab corruption (Not tainted): Acpi-ParseExt start=ffff801fb0b69030, len=80 [ 43.115206] Redzone: 0x9f911029d006462/0x5f78745f31657070.
