Subject: [Qemu-devel] [PATCH] Add support for ethtool via TARGET_SIOCETHTOOL ioctls.
Date: Fri, 16 Aug 2019 14:13:56 -0700 [thread overview]
Message-ID: <20190816211356.59244-1-scw@google.com> (raw)
The ioctl numeric values are platform-independent and determined by
the file include/uapi/linux/sockios.h in Linux kernel source code:
#define SIOCETHTOOL 0x8946
These ioctls get (or set) the field ifr_data of type char* 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.
