* Description:
* Start the oneshot timer
*
* Input Parameters:
* lower An instance of the lower-half oneshot state structure. This

* handler The function to call when when the oneshot timer expires.
* arg An opaque argument that will accompany the callback.

* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned
* on failure.
