[Qemu-devel] [PATCH v5 3/6] linux-user: Add support for SIOC<G|S>IFPFLAGS ioctls for all targets

[Aleksandar Markovic]

From: Neng Chen <address@hidden>

Add support for getting and setting 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:

  #define SIOCSIFPFLAGS 0x8934
  #define SIOCGIFPFLAGS 0x8935

These ioctls get (or set) the field ifr_flags of type short 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.
