Subject: [PATCH net-next RFC v1 1/4] devlink: Wrap trap related lists and ops in trap_mngr
Bundle the trap related lists: trap_list, trap_group_list and
trap_policer_list and trap ops like: trap_init, trap_fini,
trap_action_set... together in trap_mngr. This will be handy in the
coming patches in the set introducing traps in devlink port context.
With trap_mngr, code reuse is much simpler.
