IAGNOSTIC END
This register keeps track of the NIC local copy of the send BD ring consumer index (not the host copy which is DMAed by
the Host Coalescing engine to the host). This is shared between the Send BD Initiator and the Host Coalescing state
machines.
Note: The programmer should not write to this register—it is for internal use only to aid with debugging and
diagnostics.
