Structures, macros, and functions for working with completion rings in the driver. Completion Ring is used by the Ethernet controller to provide the status of transmitted & received packets, report errors, report status changes to the host software, and inter-function forwarding requests. In addition to the generic ring features, a completion ring can have a statistics context that has statistics periodically DMAed to host memory, along with a consumer index. bnxt_handle_async_event() handles completions not related to a specific transmit or receive ring such as link status changes which arrive on the default completion ring. Other physical or virtual functions on the same device may send an HWRM command forward request. In this case, we will pass it through unvalidated. In the future, we will be able to have the PF monitor and control VF access to the HWRM interface if needed. New HWRM Calls: bnxt_hwrm_exec_fwd_resp: Execute an encapsulated command and forward the response.
