[PATCH net-next 11/15] net: sparx5: ops out functions for getting certain array values

There is a newer version of this series
[PATCH net-next 11/15] net: sparx5: ops out functions for getting certain array values
Posted by Daniel Machon 1 month, 3 weeks ago 
Add getters for getting values in arrays: sdlb_groups and
sparx5_hsch_max_group_rate and ops out the getters, as these arrays will
differ on lan969x.
