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.
