# Form letter - net-next is closed
We have already sent a pull request for 5.10 and therefore net-next is closed for new drivers, features, and code refactoring.
Please repost when net-next reopens after 5.10-rc1 is cut.
(http://vger.kernel.org/~davem/net-next.html will not be up to date this time around, sorry about that).
RFC patches sent for review only are obviously welcome at any time.
