Subject: [patch net-next 04/16] mlxsw: spectrum_trap: Prepare mlxsw_core_trap_action_set() to handle not only action

From: Jiri Pirko <jiri@...lanox.com>

Rename function mlxsw_core_trap_action_set() to
mlxsw_core_trap_state_set() and pass bool enabled instead of action.
Figure out the action according to the enabled state there.
