Subject: [RFC PATCH] net: Remove a confusing comment of macro SIOCDEVPRIVATE

I have been reading the NET related header files recently.  I found
there is a macro "#define SIOCDEVPRIVATE 0x89F0" defined in
include/uapi/linux/sockios.h which is useful for private controls of net
devices.  When I read this section:

/* Device private ioctl calls */

/*
 *	These 16 ioctls are available to devices via the do_ioctl() device
 *	vector. Each device should include this file and redefine these names
 *	as their own. Because these are device dependent it is a good idea
 *	_NOT_ to issue them to random objects and hope.
 *
 *	THESE IOCTLS ARE _DEPRECATED_ AND WILL DISAPPEAR IN 2.5.X -DaveM
 */

I notice there is a string in the comment:
"THESE IOCTLS ARE _DEPRECATED_ AND WILL DISAPPEAR IN 2.5.X -DaveM"
which makes me confused.  Because, there are still a lot of devices or
subsystems using this macro, for example, ethernet, appletalk,
usb/rtl8150 ..., etc.

Therefore, I make this patch to remove the confusing comment.
