#     Merge tag 'net-next-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
#     
#     Pull networking changes from Jakub Kicinski:
#      "WiFi 7 and sendpage changes are the biggest pieces of work for this
#       release. The latter will definitely require fixes but I think that we
#       got it to a reasonable point.
#     
#       Core:
#     
#        - Rework the sendpage & splice implementations
#     
#          Instead of feeding data into sockets page by page extend sendmsg
#          handlers to support taking a reference on the data, controlled by a
#          new flag called MSG_SPLICE_PAGES
#     
#          Rework the handling of unexpected-end-of-file to invoke an
#          additional callback instead of trying to predict what the right
#          combination of MORE/NOTLAST flags is
#     
#          Remove the MSG_SENDPAGE_NOTLAST flag completely
#     
#        - Implement SCM_PIDFD, a new type of CMSG type analogous to
#          SCM_CREDENTIALS, but it contains pidfd instead of plain pid
#     
#        - Enable socket busy polling with CONFIG_RT
#     
#        - Improve reliability and efficiency of reporting for ref_tracker
#     
#        - Auto-generate a user space C library for various Netlink families
#     
#       Protocols:
#     
#        - Allow TCP to shrink the advertised window when necessary, prevent
#          sk_rcvbuf auto-tuning from growing the window all the way up to
#          tcp_rmem[2]
#     
#        - Use per-VMA locking for "page-flipping" TCP receive zerocopy
#     
#        - Prepare TCP for device-to-device data transfers, by making sure
#          that payloads are always attached to skbs as page frags
#     
#        - Make the backoff time for the first N TCP SYN retransmissions
#          linear. Exponential backoff is unnecessarily conservative
#     
#        - Create a new MPTCP getsockopt to retrieve all info
#          (MPTCP_FULL_INFO)
#     
#        - Avoid waking up applications using TLS sockets until we have a full
#          record
#     
#        - Allow using kernel memory for protocol ioctl callbacks, paving the
#          way to issuing ioctls over io_uring
#     
#        - Add nolocalbypass option to VxLAN, forcing packets to be fully
#          encapsulated even if they are destined for a local IP address
#     
#        - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
#          in-kernel ECMP implementation (e.g. Open vSwitch) select the same
#          link for all packets. Support L4 symmetric hashing in Open vSwitch
#     
#        - PPPoE: make number of hash bits configurable
#     
#        - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
#          (ipconfig)
#     
#        - Add layer 2 miss indication and filtering, allowing higher layers
#          (e.g. ACL filters) to make forwarding decisions based on whether
#          packet matched forwarding state in lower devices (bridge)
#     
#        - Support matching on Connectivity Fault Management (CFM) packets
#     
#        - Hide the "link becomes ready" IPv6 messages by demoting their
#          printk level to debug
#     
#        - HSR: don't enable promiscuous mode if device offloads the proto
#     
#        - Support active scanning in IEEE 802.15.4
#     
#        - Continue work on Multi-Link Operation for WiFi 7
#     
#       BPF:
#     
#        - Add precision propagation for subprogs and callbacks. This allows
#          maintaining verification efficiency when subprograms are used, or
#          in fact passing the verifier at all for complex programs,
#          especially those using open-coded iterators
#     
#        - Improve BPF's {g,s}setsockopt() length handling. Previously BPF
#          assumed the length is always equal to the amount of written data.
#          But some protos allow passing a NULL buffer to discover what the
#          output buffer *should* be, without writing anything
#     
#        - Accept dynptr memory as memory arguments passed to helpers
#     
#        - Add routing table ID to bpf_fib_lookup BPF helper
#     
#        - Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands
#     
#        - Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
#          maps as read-only)
#     
#        - Show target_{obj,btf}_id in tracing link fdinfo
#     
#        - Addition of several new kfuncs (most of the names are
#          self-explanatory):
#           - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
#             bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
#             and bpf_dynptr_clone().
#           - bpf_task_under_cgroup()
#           - bpf_sock_destroy() - force closing sockets
#           - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
#     
#       Netfilter:
#     
#        - Relax set/map validation checks in nf_tables. Allow checking
#          presence of an entry in a map without using the value
#     
#        - Increase ip_vs_conn_tab_bits range for 64BIT builds
#     
#        - Allow updating size of a set
#     
#        - Improve NAT tuple selection when connection is closing
#     
#       Driver API:
#     
#        - Integrate netdev with LED subsystem, to allow configuring HW
#          "offloaded" blinking of LEDs based on link state and activity
#          (i.e. packets coming in and out)
#     
#        - Support configuring rate selection pins of SFP modules
#     
#        - Factor Clause 73 auto-negotiation code out of the drivers, provide
#          common helper routines
#     
#        - Add more fool-proof helpers for managing lifetime of MDIO devices
#          associated with the PCS layer
#     
#        - Allow drivers to report advanced statistics related to Time Aware
#          scheduler offload (taprio)
#     
#        - Allow opting out of VF statistics in link dump, to allow more VFs
#          to fit into the message
#
