Please find the DualPI2 patch v17.

This patch serise adds DualPI Improved with a Square (DualPI2) with following features:

• Supports congestion controls that comply with the Prague requirements in RFC9331 (e.g. TCP-Prague)
• Coupled dual-queue that separates the L4S traffic in a low latency queue (L-queue), without harming remaining traffic that is scheduled in classic queue (C-queue) due to congestion-coupling using PI2 as defined in RFC9332
• Configurable overload strategies
• Use of sojourn time to reliably estimate queue delay
• Supports ECN L4S-identifier (IP.ECN==0b*1) to classify traffic into respective queues

For more details of DualPI2, please refer IETF RFC9332 (https://datatracker.ietf.org/doc/html/rfc9332).

## 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.
