> This commit consists of 3 patches: > > patch1 (1/3): > 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. > > patch2 (2/3): > Modified netronome nfp flower action to use VLAN helper functions instead > of accessing/referencing TC act_vlan private structures directly. > > patch3 (3/3): > 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. > All functions now use an RCU dereferenced pointer to access the VLAN action > context. Modified helper functions used by other modules, to use the RCU as > opposed to directly accessing the structure. > > As part of this review, there were some changes suggested by reviewers. > I have incorporated all the changes that were requested. ... Series applied, thank you.
