Rafał Miłecki 981f5f7e40 kernel: fix refcnt leak in LED netdev trigger on interface rename
Renaming a netdev-trigger-tracked interface was resulting in an
unbalanced dev_hold().

Example:
> iw phy phy0 interface add foo type __ap
> echo netdev > trigger
> echo foo > device_name
> ip link set foo name bar
> iw dev bar del
[  237.355366] unregister_netdevice: waiting for bar to become free. Usage count = 1
[  247.435362] unregister_netdevice: waiting for bar to become free. Usage count = 1
[  257.545366] unregister_netdevice: waiting for bar to become free. Usage count = 1

Above problem was caused by trigger checking a dev->name which obviously
changes after renaming an interface. It meant missing all further events
including the NETDEV_UNREGISTER which is required for calling dev_put().

This change fixes that by:
1) Comparing device struct *address* for notification-filtering purposes
2) Dropping unneeded NETDEV_CHANGENAME code (no behavior change)

This is the buildsystem for the LEDE Linux distribution.

Please use "make menuconfig" to choose your preferred
configuration for the toolchain and firmware.

You need to have installed gcc, binutils, bzip2, flex, python, perl, make,
find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers.

Run "./scripts/feeds update -a" to get all the latest package definitions
defined in feeds.conf / feeds.conf.default respectively
and "./scripts/feeds install -a" to install symlinks of all of them into
package/feeds/.

Use "make menuconfig" to configure your image.

Simply running "make" will build your firmware.
It will download all sources, build the cross-compile toolchain, 
the kernel and all choosen applications.

To build your own firmware you need to have access to a Linux, BSD or MacOSX system
(case-sensitive filesystem required). Cygwin will not be supported because of
the lack of case sensitiveness in the file system.
