bcm53xx: add support basic for kernel 4.3 The files directory is now split up into the files which are needed for every kernel version and the files only needed by kernel 4.1. The files in files-4.1 are already merged into mainline kernel 4.3. This patch only removed patches which were merged into mainline kernel 4.3.
