## Form letter - net-next-closed

We have already submitted our pull request with net-next material for v7.1,
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 Apr 27th.

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