[PATCH net-next v3 0/2] net/sched: remove spinlock from 'csum' action

2018-01-22 Thread Davide Caratti
Similarly to what has been done earlier with other actions [1][2], this series tries to improve the performance of 'csum' tc action, removing a spinlock in the data path. Patch 1 lets act_csum use per-CPU counters; patch 2 removes spin_{,un}lock_bh() calls from the act() method. test procedure
