# Form letter - net-next is closed

We have already sent the networking pull request for 6.1
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 6.1-rc1 is cut.

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