 NPA Reporters

-The NPA reporters are responsible for reporting and recovering the following group of errors
+The NPA reporters are responsible for reporting and recovering the following group of errors:
+
 1. GENERAL events
+
    - Error due to operation of unmapped PF.
    - Error due to disabled alloc/free for other HW blocks (NIX, SSO, TIM, DPI and AURA).
+
 2. ERROR events
+
    - Fault due to NPA_AQ_INST_S read or NPA_AQ_RES_S write.
    - AQ Doorbell Error.
+
 3. RAS events
+
    - RAS Error Reporting for NPA_AQ_INST_S/NPA_AQ_RES_S.
+
 4. RVU events
+
    - Error due to unmapped slot.
