## Form letter - net-next-closed

The merge window for v6.9 has begun and we have already posted our pull
request. 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 March 25th.

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