## Form letter - net-next-closed
The merge window for v6.16 has begun and therefore net-next is closed
for new drivers, features, code refactoring and optimizations.
Please repost when net-next reopens after June 9th.
RFC patches sent for review only are obviously welcome at any time.
See: https://www.kernel.org/doc/html/next/process/maintainer-netdev.html#development-cycle
