A bit of a bad timing, the merge window for 6.5 has just opened and we're busy settling the bugs in linux-next right now. So you will need to repost this change in 2 weeks... ## Form letter - net-next-closed The merge window for v6.5 has begun 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 10th. RFC patches sent for review only are obviously welcome at any time.
