      Pull networking updates from Jakub Kicinski:
       "Core
        ----
      
         - Support TCPv6 segmentation offload with super-segments larger than
           64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).
      
         - Generalize skb freeing deferral to per-cpu lists, instead of
           per-socket lists.
      
         - Add a netdev statistic for packets dropped due to L2 address
           mismatch (rx_otherhost_dropped).
      
         - Continue work annotating skb drop reasons.
      
         - Accept alternative netdev names (ALT_IFNAME) in more netlink
           requests.
      
         - Add VLAN support for AF_PACKET SOCK_RAW GSO.
      
         - Allow receiving skb mark from the socket as a cmsg.
      
         - Enable memcg accounting for veth queues, sysctl tables and IPv6.
      
        BPF
        ---
      
         - Add libbpf support for User Statically-Defined Tracing (USDTs).
      
         - Speed up symbol resolution for kprobes multi-link attachments.
      
         - Support storing typed pointers to referenced and unreferenced
           objects in BPF maps.
      
         - Add support for BPF link iterator.
      
         - Introduce access to remote CPU map elements in BPF per-cpu map.
      
         - Allow middle-of-the-road settings for the
           kernel.unprivileged_bpf_disabled sysctl.
      
         - Implement basic types of dynamic pointers e.g. to allow for
           dynamically sized ringbuf reservations without extra memory copies.
      
        Protocols
        ---------
      
         - Retire port only listening_hash table, add a second bind table
           hashed by port and address. Avoid linear list walk when binding to
           very popular ports (e.g. 443).
      
         - Add bridge FDB bulk flush filtering support allowing user space to
           remove all FDB entries matching a condition.
      
         - Introduce accept_unsolicited_na sysctl for IPv6 to implement
           router-side changes for RFC9131.
      
         - Support for MPTCP path manager in user space.
      
         - Add MPTCP support for fallback to regular TCP for connections that
           have never connected additional subflows or transmitted
           out-of-sequence data (partial support for RFC8684 fallback).
      
         - Avoid races in MPTCP-level window tracking, stabilize and improve
           throughput.
      
         - Support lockless operation of GRE tunnels with seq numbers enabled.
      
         - WiFi support for host based BSS color collision detection.
      
         - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.
      
         - Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).
      
         - Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).
      
         - Allow matching on the number of VLAN tags via tc-flower.
      
         - Add tracepoint for tcp_set_ca_state().
      
        Driver API
        ----------
      
         - Improve error reporting from classifier and action offload.
      
         - Add support for listing line cards in switches (devlink).
      
         - Add helpers for reporting page pool statistics with ethtool -S.
      
         - Add support for reading clock cycles when using PTP virtual clocks,
           instead of having the driver convert to time before reporting. This
           makes it possible to report time from different vclocks.
      
         - Support configuring low-latency Tx descriptor push via ethtool.
      
         - Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

      Pull printk updates from Petr Mladek:
      
       - Offload writing printk() messages on consoles to per-console
         kthreads.
      
         It prevents soft-lockups when an extensive amount of messages is
         printed. It was observed, for example, during boot of large systems
         with a lot of peripherals like disks or network interfaces.
      
         It prevents live-lockups that were observed, for example, when
         messages about allocation failures were reported and a CPU handled
         consoles instead of reclaiming the memory. It was hard to solve even
         with rate limiting because it would need to take into account the
         amount of messages and the speed of all consoles.
      
         It is a must to have for real time. Otherwise, any printk() might
         break latency guarantees.
      
         The per-console kthreads allow to handle each console on its own
         speed. Slow consoles do not longer slow down faster ones. And
         printk() does not longer unpredictably slows down various code paths.
      
         There are situations when the kthreads are either not available or
         not reliable, for example, early boot, suspend, or panic. In these
         situations, printk() uses the legacy mode and tries to handle
         consoles immediately.
      
       - Add documentation for the printk index.
