Implements the core error processing infrastructure
for:
- REO exception ring and
- WBM SW Release ring.
Individual error handling (e.g Defragmentation) will
be added going forward.
In this first check-in all frames routed to the WBM release ring
are dropped except MC/BC packet that get routed to this ring,
due to the default configuration (MC/BC packets cause NULL queue
descriptor violation).
