#     Merge tag 'net-next-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
#     
#     Pull networking updates from Paolo Abeni:
#      "Core:
#     
#        - Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
#          default value allows for better BIG TCP performances
#     
#        - Reduce compound page head access for zero-copy data transfers
#     
#        - RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when
#          possible
#     
#        - Threaded NAPI improvements, adding defer skb free support and
#          unneeded softirq avoidance
#     
#        - Address dst_entry reference count scalability issues, via false
#          sharing avoidance and optimize refcount tracking
#     
#        - Add lockless accesses annotation to sk_err[_soft]
#     
#        - Optimize again the skb struct layout
#     
#        - Extends the skb drop reasons to make it usable by multiple
#          subsystems
#     
#        - Better const qualifier awareness for socket casts
#     
#       BPF:
#     
#        - Add skb and XDP typed dynptrs which allow BPF programs for more
#          ergonomic and less brittle iteration through data and
#          variable-sized accesses
#     
#        - Add a new BPF netfilter program type and minimal support to hook
#          BPF programs to netfilter hooks such as prerouting or forward
#     
#        - Add more precise memory usage reporting for all BPF map types
#     
#        - Adds support for using {FOU,GUE} encap with an ipip device
#          operating in collect_md mode and add a set of BPF kfuncs for
#          controlling encap params
#     
#        - Allow BPF programs to detect at load time whether a particular
#          kfunc exists or not, and also add support for this in light
#          skeleton
#     
#        - Bigger batch of BPF verifier improvements to prepare for upcoming
#          BPF open-coded iterators allowing for less restrictive looping
#          capabilities
#     
#        - Rework RCU enforcement in the verifier, add kptr_rcu and enforce
#          BPF programs to NULL-check before passing such pointers into kfunc
#     
#        - Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and
#          in local storage maps
#     
#        - Enable RCU semantics for task BPF kptrs and allow referenced kptr
#          tasks to be stored in BPF maps
#     
#        - Add support for refcounted local kptrs to the verifier for allowing
#          shared ownership, useful for adding a node to both the BPF list and
#          rbtree
#     
#        - Add BPF verifier support for ST instructions in
#          convert_ctx_access() which will help new -mcpu=v4 clang flag to
#          start emitting them
#     
#        - Add ARM32 USDT support to libbpf
#     
#        - Improve bpftool's visual program dump which produces the control
#          flow graph in a DOT format by adding C source inline annotations
#     
#       Protocols:
#     
#        - IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
#          indicates the provenance of the IP address
#     
#        - IPv6: optimize route lookup, dropping unneeded R/W lock acquisition
#     
#        - Add the handshake upcall mechanism, allowing the user-space to
#          implement generic TLS handshake on kernel's behalf
#     
#        - Bridge: support per-{Port, VLAN} neighbor suppression, increasing
#          resilience to nodes failures
#     
#        - SCTP: add support for Fair Capacity and Weighted Fair Queueing
#          schedulers
#     
#        - MPTCP: delay first subflow allocation up to its first usage. This
#          will allow for later better LSM interaction
#     
#        - xfrm: Remove inner/outer modes from input/output path. These are
#          not needed anymore
#     
#        - WiFi:
#           - reduced neighbor report (RNR) handling for AP mode
#           - HW timestamping support
#           - support for randomized auth/deauth TA for PASN privacy
#           - per-link debugfs for multi-link
#           - TC offload support for mac80211 drivers
#           - mac80211 mesh fast-xmit and fast-rx support
#           - enable Wi-Fi 7 (EHT) mesh support
#     
#       Netfilter:
#     
#        - Add nf_tables 'brouting' support, to force a packet to be routed
#          instead of being bridged
#     
#        - Update bridge netfilter and ovs conntrack helpers to handle IPv6
#          Jumbo packets properly, i.e. fetch the packet length from
#          hop-by-hop extension header. This is needed for BIT TCP support
#     
#        - The iptables 32bit compat interface isn't compiled in by default
#          anymore
#     
#        - Move ip(6)tables builtin icmp matches to the udptcp one. This has
#          the advantage that icmp/icmpv6 match doesn't load the
#          iptables/ip6tables modules anymore when iptables-nft is used
#     
#        - Extended netlink error report for netdevice in flowtables and
#          netdev/chains. Allow for incrementally add/delete devices to netdev
#          basechain. Allow to create netdev chain without device
#     
#       Driver API:
#     
#        - Remove redundant Device Control Error Reporting Enable, as PCI core
#          has already error reporting enabled at enumeration time
#     
#        - Move Multicast DB netlink handlers to core, allowing devices other
#          then bridge to use them
#     
#        - Allow the page_pool to directly recycle the pages from safely
#          localized NAPI
#     
#        - Implement lockless TX queue stop/wake combo macros, allowing for
#          further code de-duplication and sanitization
#     
#        - Add YNL support for user headers and struct attrs
#     
#        - Add partial YNL specification for devlink
#     
#        - Add partial YNL specification for ethtool
#     
#        - Add tc-mqprio and tc-taprio support for preemptible traffic classes
#     
#        - Add tx push buf len param to ethtool, specifies the maximum number
#          of bytes of a transmitted packet a driver can push directly to the
#          underlying device
#     
#        - Add basic LED support for switch/phy
#     
#        - Add NAPI documentation, stop relaying on external links
#     
#        - Convert dsa_master_ioctl() to netdev notifier. This is a
#          preparatory work to make the hardware timestamping layer selectable
#          by user space
#     
#        - Add transceiver support and improve the error messages for CAN-FD
#          controllers
