Linus Torvalds f86d1fbbe7 Networking changes for 6.0.
Core
 ----
 
  - Refactor the forward memory allocation to better cope with memory
    pressure with many open sockets, moving from a per socket cache to
    a per-CPU one
 
  - Replace rwlocks with RCU for better fairness in ping, raw sockets
    and IP multicast router.
 
  - Network-side support for IO uring zero-copy send.
 
  - A few skb drop reason improvements, including codegen the source file
    with string mapping instead of using macro magic.
 
  - Rename reference tracking helpers to a more consistent
    netdev_* schema.
 
  - Adapt u64_stats_t type to address load/store tearing issues.
 
  - Refine debug helper usage to reduce the log noise caused by bots.
 
 BPF
 ---
  - Improve socket map performance, avoiding skb cloning on read
    operation.
 
  - Add support for 64 bits enum, to match types exposed by kernel.
 
  - Introduce support for sleepable uprobes program.
 
  - Introduce support for enum textual representation in libbpf.
 
  - New helpers to implement synproxy with eBPF/XDP.
 
  - Improve loop performances, inlining indirect calls when
    possible.
 
  - Removed all the deprecated libbpf APIs.
 
  - Implement new eBPF-based LSM flavor.
 
  - Add type match support, which allow accurate queries to the
    eBPF used types.
 
  - A few TCP congetsion control framework usability improvements.
 
  - Add new infrastructure to manipulate CT entries via eBPF programs.
 
  - Allow for livepatch (KLP) and BPF trampolines to attach to the same
    kernel function.
 
 Protocols
 ---------
 
  - Introduce per network namespace lookup tables for unix sockets,
    increasing scalability and reducing contention.
 
  - Preparation work for Wi-Fi 7 Multi-Link Operation (MLO) support.
 
  - Add support to forciby close TIME_WAIT TCP sockets via user-space
    tools.
 
  - Significant performance improvement for the TLS 1.3 receive path,
    both for zero-copy and not-zero-copy.
 
  - Support for changing the initial MTPCP subflow priority/backup
    status
 
  - Introduce virtually contingus buffers for sockets over RDMA,
    to cope better with memory pressure.
 
  - Extend CAN ethtool support with timestamping capabilities
 
  - Refactor CAN build infrastructure to allow building only the needed
    features.
 
 Driver API
 ----------
 
  - Remove devlink mutex to allow parallel commands on multiple links.
 
  - Add support for pause stats in distributed switch.
 
  - Implement devlink helpers to query and flash line cards.
 
  - New helper for phy mode to register conversion.
