Felix Fietkau 7224c5d249 mac80211: fix crash when using mesh (11s) VIF together with another VIF
llid_in_use needs to be limited to stations of the same VIF, otherwise it
will cause a NULL deref as the sta_info of non-mesh-VIFs don't have
sta->mesh set.

Steps to reproduce:

   modprobe mac80211_hwsim channels=2
   iw phy phy0 interface add ibss0 type ibss
   iw phy phy0 interface add mesh0 type mp
   iw phy phy1 interface add ibss1 type ibss
   iw phy phy1 interface add mesh1 type mp
   ip link set ibss0 up
   ip link set mesh0 up
   ip link set ibss1 up
   ip link set mesh1 up
   iw dev ibss0 ibss join foo 2412
   iw dev ibss1 ibss join foo 2412
   # Ensure that ibss0 and ibss1 are actually associated; I often need to
   # leave and join the cell on ibss1 a second time.
   iw dev mesh0 mesh join bar
   iw dev mesh1 mesh join bar # crash

This is the buildsystem for the OpenWrt Linux distribution.

Please use "make menuconfig" to configure your appreciated
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.

You can use "scripts/flashing/flash.sh" for remotely updating your embedded
system via tftp.

The OpenWrt system is documented in docs/. You will need a LaTeX distribution
and the tex4ht package to build the documentation. Type "make -C docs/" to build it.

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.
