The event timer adapter[1] provides APIs to configure an event timer device
that allows an application to arm timers which on expiry push events to an
event device such as OcteonTx SSO.
The OcteonTx TIM is a co-processor that can be configured as an event timer
adapter which can be used by an application to manage event timers.
The TIM co-processor processes the event timers registered and pushes
expired event timers to SSO based on the event queue, schedule type, flow
id etc. provided as rte_event while arming the event timer. It maintains
event timers with high precision and time granularity of 1us (microsecond).
