** Function         nfa_nv_ci_write
**
** Description      This function sends an event to NFAA indicating the phone
**                  has written the number of bytes specified in the call-out
**                  function, nfa_nv_co_write (), and is ready for more data.
**                  This function is used to control the TX data flow.
**                  Note: The data buffer is released by the stack aioer
**                        calling this function.
**
** Parameters       status - NFA_NV_CO_OK, NFA_NV_CO_NOSPACE, or NFA_NV_CO_FAIL
**                  evt - Used Internally by NFA -> MUST be same value passed
**                       in call-out function.

** Returns          void

** Function         nfa_nv_ci_read
**
** Description      This function sends an event to NFA indicating the phone has
**                  read in the requested amount of data specified in the
**                  nfa_nv_co_read () call-out function.  It should only be called
**                  when the requested number of bytes has been read.
**
** Parameters       num_bytes_read - number of bytes read into the buffer
**                      specified in the read callout-function.
**                  status - NFA_NV_CO_OK if full buffer of data,
**                           NFA_NV_CO_EOF if the end of file has been reached,
**                           NFA_NV_CO_FAIL if an error has occurred.
