# 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.
