The main goal of this patch series is to introduce the ability to disable SR-IOV VFs by writing zero to the sriov_numvfs sysfs file. Alongside this, a few additional enhancements and fixes have been implemented. Summary of Changes: Patch #1: Preserves the entire ADF_GENERAL_SEC section during device shutdown. Patch #2: Adjusts the order in adf_dev_stop() to disable IOV before stopping the AEs. Patch #3: Adds support for the ADF_VF2PF_MSGTYPE_RESTARTING_COMPLETE message to ensure proper VF shutdown notification. Patch #4: Fixes a race condition by setting the vf->restarting flag before sending the restart message. Patch #5: Enables SR-IOV VF disablement through the sysfs interface.
