Advance the qed* drivers to use firmware 8.33.1.0: Modify core driver (qed) to utilize the new FW and initialize the device with it. This is the lion's share of the patch, and includes changes to FW interface files, device initialization flows, FW interaction flows, and debug collection flows. Modify Ethernet driver (qede) to make use of new FW in fastpath. Modify RoCE/iWARP driver (qedr) to make use of new FW in fastpath. Modify FCoE driver (qedf) to make use of new FW in fastpath. Modify iSCSI driver (qedi) to make use of new FW in fastpath.
