From 4bdcd79e3e4127c2813a4caebd38c96f1974983e Mon Sep 17 00:00:00 2001 From: Neng Chen Date: Sun, 19 May 2019 18:15:24 +0200 Subject: [PATCH] linux-user: Add support for SIOCIFPFLAGS ioctls for all targets 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.
