Pull networking updates from Paolo Abeni:
 "Core & protocols:

   - Improve drop account scalability on NUMA hosts for RAW and UDP
     sockets and the backlog, almost doubling the Pps capacity under DoS

   - Optimize the UDP RX performance under stress, reducing contention,
     revisiting the binary layout of the involved data structs and
     implementing NUMA-aware locking. This improves UDP RX performance
     by an additional 50%, even more under extreme conditions

   - Add support for PSP encryption of TCP connections; this mechanism
     has some similarities with IPsec and TLS, but offers superior HW
     offloads capabilities

   - Ongoing work to support Accurate ECN for TCP. AccECN allows more
     than one congestion notification signal per RTT and is a building
     block for Low Latency, Low Loss, and Scalable Throughput (L4S)

   - Reorganize the TCP socket binary layout for data locality, reducing
     the number of touched cachelines in the fastpath

   - Refactor skb deferral free to better scale on large multi-NUMA
     hosts, this improves TCP and UDP RX performances significantly on
     such HW

   - Increase the default socket memory buffer limits from 256K to 4M to
     better fit modern link speeds

   - Improve handling of setups with a large number of nexthop, making
     dump operating scaling linearly and avoiding unneeded
     synchronize_rcu() on delete

   - Improve bridge handling of VLAN FDB, storing a single entry per
     bridge instead of one entry per port; this makes the dump order of
     magnitude faster on large switches

   - Restore IP ID correctly for encapsulated packets at GSO
     segmentation time, allowing GRO to merge packets in more scenarios

   - Improve netfilter matching performance on large sets

   - Improve MPTCP receive path performance by leveraging recently
     introduced core infrastructure (skb deferral free) and adopting
     recent TCP autotuning changes

   - Allow bridges to redirect to a backup port when the bridge port is
     administratively down

   - Introduce MPTCP 'laminar' endpoint that con be used only once per
     connection and simplify common MPTCP setups

   - Add RCU safety to dst->dev, closing a lot of possible races

   - A significant crypto library API for SCTP, MPTCP and IPv6 SR,
     reducing code duplication

   - Supports pulling data from an skb frag into the linear area of an
     XDP buffer

  Things we sprinkled into general kernel code:

   - Generate netlink documentation from YAML using an integrated YAML
     parser

  Driver API:

   - Support using IPv6 Flow Label in Rx hash computation and RSS queue
     selection

   - Introduce API for fetching the DMA device for a given queue,
     allowing TCP zerocopy RX on more H/W setups

   - Make XDP helpers compatible with unreadable memory, allowing more
     easily building DevMem-enabled drivers with a unified XDP/skbs
     datapath

   - Add a new dedicated ethtool callback enabling drivers to provide
     the number of RX rings directly, improving efficiency and clarity
     in RX ring queries and RSS configuration

   - Introduce a burst period for the health reporter, allowing better
     handling of multiple errors due to the same root cause

   - Support for DPLL phase offset exponential moving average,
     controlling the average smoothing factor

  Device drivers:

   - Add a new Huawei driver for 3rd gen NIC (hinic3)

   - Add a new SpacemiT driver for K1 ethernet MAC

   - Add a generic abstraction for shared memory communication
     devices (dibps)

   - Ethernet high-speed NICs:
      - nVidia/Mellanox:
         - Use multiple per-queue doorbell, to avoid MMIO contention
           issues

           SR-IOV VFs to sibling PFs
         - support RSS for IPSec offload
         - support exposing raw cycle counters in PTP and mlx5
         - support for disabling host PFs.
