Subject: [Qemu-devel] [PATCH 3/4] linux-user: Add support the SIOCSIFPFLAGS and SIOCGIFPFLAGS ioctls
Date: Tue, 23 Apr 2019 19:35:25 +0200	[thread overview]
Message-ID: <1556040926-23931-4-git-send-email-aleksandar.markovic@rt-rk.com> (raw)
In-Reply-To: <1556040926-23931-1-git-send-email-aleksandar.markovic@rt-rk.com>

From: Neng Chen <nchen@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.
