When a queue is restarted, it sets MRU to 0 for stopping packet flow. MRU variable is a member of vnic_info[], the first vnic_info is default and the second is ntuple. Only when ntuple is enabled(ethtool -K eth0 ntuple on), vnic_info for ntuple is allocated in init logic. The bp->nr_vnics indicates how many vnic_info are allocated. However bnxt_queue_{start | stop}() accesses vnic_info[BNXT_VNIC_NTUPLE] regardless of ntuple state.
