From: Neng Chen <nc...@wavecomp.com>
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.

Applied to my linux-user branch.
Thanks,
