From: Mateusz Palczewski <mateusz.palczewski@intel.com> stable inclusion from linux-4.19.221 commit 4b689c3619619778fe58bc35adac858e61e9428e -------------------------------- commit 8aa55ab422d9d0d825ebfb877702ed661e96e682 upstream. After setting pre-set combined to 16 queues and reserving 16 queues by tc qdisc, pre-set maximum combined queues returned to default value after VF reset being 4 and this generated errors during removing tc. Fixed by removing clear num_req_queues before reset VF.
