[PATCH net-next 2/2] net sched act_vlan: VLAN action rewrite to use RCU lock/unlock and update

Using a spinlock in the VLAN action causes performance issues when the VLAN action is used on multiple cores. Rewrote the VLAN action to use RCU read locking for reads and updates instead. Signed-off-by: Manish Kurup --- include/net/tc_act/tc_vlan.h | 21 - net/sched/act_vlan.c

[PATCH net-next 1/2] net sched act_vlan: Change stats update to use per-core stats

The VLAN action maintains one set of stats across all cores, and uses a spinlock to synchronize updates to it from the same. Changed this to use a per-CPU stats context instead. This change will result in better performance. Signed-off-by: Manish Kurup --- net/sched/act_vlan.c | 10
