## Form letter - net-next-closed

The merge window for v6.11 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 July 29th.

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