NIC DIAGNOSTIC RETURN RINGS PRODUCER INDEX REGISTER (OFFSET
0X3C80–0X3C83)—BCM5906 ONLY
This register keeps track of the NIC local copy of the return ring producer index (not the host copy which is DMAed by the
Host Coalescing engine to the host).
Note: The programmer should not write to these registers—they are for internal use only to aid with debugging
and diagnostics.
