From: Neng Chen <nc...@wavecomp.com> Add support for setting and getting extended (private) flags of a network device via SIOCSIFPFLAGS and SIOCGIFPFLAGS ioctls.
The ioctl numeric value is platform-independent and determined by the file include/uapi/linux/sockios.h in Linux kernel source code: #define SIOCSIFPFLAGS 0x8934 The ioctls set and get field ifr_flags of type short in the structure ifreq. Such functionality in QEMU is achieved using MK_STRUCT() and MK_PTR() macros with an appropriate argument.
