| The patches-* subdirectories contain the kernel patches applied for every | 
 | OpenWrt target. All patches should be named 'NNN-lowercase_shortname.patch' | 
 | and sorted into the following categories: | 
 |  | 
 | 0xx - upstream backports | 
 | 1xx - code awaiting upstream merge | 
 | 2xx - kernel build / config / header patches | 
 | 3xx - architecture specific patches | 
 | 4xx - mtd related patches (subsystem and drivers) | 
 | 5xx - filesystem related patches | 
 | 6xx - generic network patches | 
 | 7xx - network / phy driver patches | 
 | 8xx - other drivers | 
 | 9xx - uncategorized other patches | 
 |  | 
 | ALL patches must be in a way that they are potentially upstreamable, meaning: | 
 |  | 
 | - they must contain a proper subject | 
 | - they must contain a proper commit message explaining what they change | 
 | - they must contain a valid Signed-off-by line |
