net/bnxt: add completion ring 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.

net/bnxt: handle VF/PF initialization appropriately 1) For a VF, query the firmware to determine if a MAC address is already configured. If not configure a random default MAC address. 2) Do not initialize the default completion ring in bnxt_alloc_hwrm_rings(). 3) While registering for async events with the firmware, use func_vf_cfg for a VF and use func_cfg for a PF. 4) Query the VNIC plcmode config using the bnxt_hwrm_vnic_plcmodes_qcfg before a VNIC is updated. Reconfigure the VNIC with the plcmode configuration queried earlier. Not doing this could overwrite the plcmodes in some cases. 5) Reorg the bnxt_handle_fwd_req to properly handle the forwarded requests. The previous code did not handle it completely.

net/bnxt: add completion ring 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.

net/bnxt: handle VF/PF initialization appropriately 1) For a VF, query the firmware to determine if a MAC address is already configured. If not configure a random default MAC address. 2) Do not initialize the default completion ring in bnxt_alloc_hwrm_rings(). 3) While registering for async events with the firmware, use func_vf_cfg for a VF and use func_cfg for a PF. 4) Query the VNIC plcmode config using the bnxt_hwrm_vnic_plcmodes_qcfg before a VNIC is updated. Reconfigure the VNIC with the plcmode configuration queried earlier. Not doing this could overwrite the plcmodes in some cases. 5) Reorg the bnxt_handle_fwd_req to properly handle the forwarded requests. The previous code did not handle it completely.

On receiving this notification, the PMD shall quiesce itself and poll on the HWRM_VER_GET FW command at regular intervals. Once the VER_GET command succeeds, the driver should go through the rediscovery process and re-initialize the device. Also register with FW for the reset notify async event.
