# Form letter - net-next is closed

The merge window for Linux 6.0 has started and therefore 
net-next is closed for new drivers, features, code refactoring 
and optimizations. We are currently accepting bug fixes only.

Please repost when net-next reopens after 6.0-rc1 is cut.

RFC patches sent for review only are obviously welcome at any time.
