When user had created a FD rule, all the aRFS rules should be clear up. HNS3 process flow as below: 1.get spin lock of fd_ruls_list 2.clear up all aRFS rules 3.release lock 4.get spin lock of fd_ruls_list 5.creat a rules 6.release lock; There is a short period of time between step 3 and step 4, which would creatting some new aRFS FD rules if driver was receiving packet. So refactor the fd_rule_lock to fix it. Fixes: 44122887 ("net: hns3: refine the flow director handle") Signed-off-by:
