[Qemu-devel] [PATCH] linux-user: Support the SIOCSIFPFLAGS and SIOCGIFPFLAGS ioctls |

From: Neng Chen <address@hidden>
Add support for setting and getting extended (private) flags
of a network device via SIOCSIFPFLAGS and SIOCGIFPFLAGS ioctls.
The ioctl numeric values are platform-independent and determined
by the file include/uapi/linux/sockios.h in Linux kernel source
code.
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.
