# 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.
