Subject: [PATCH v16 01/13] hw/pci: Rename has_power to enabled
Date: Fri, 13 Sep 2024 12:44:29 +0900	[thread overview]
Message-ID: <20240913-reuse-v16-1-d016b4b4f616@daynix.com> (raw)
In-Reply-To: <20240913-reuse-v16-0-d016b4b4f616@daynix.com>

The renamed state will not only represent powering state of PFs, but
also represent SR-IOV VF enablement in the future.
