X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-Patchwork-Original-From: Shu-Chun Weng via Qemu-devel From: "Zhijian Li (Fujitsu)\" via" Reply-To: Shu-Chun Weng Cc: arunkaly@google.com, qemu-devel@nongnu.org, Shu-Chun Weng Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP The ioctl numeric values are platform-independent and determined by the file include/uapi/linux/sockios.h in Linux kernel source code: #define SIOCETHTOOL 0x8946 These ioctls get (or set) the field ifr_data of type char* in the structure ifreq. Such functionality is achieved in QEMU by using MK_STRUCT() and MK_PTR() macros with an appropriate argument, as it was done for existing similar cases.
