Pull networking updates from Paolo Abeni:
 "Core:

   - Increase size limits for to-be-sent skb frag allocations. This
     allows tun, tap devices and packet sockets to better cope with
     large writes operations

   - Store netdevs in an xarray, to simplify iterating over netdevs

   - Refactor nexthop selection for multipath routes

   - Improve sched class lifetime handling

   - Add backup nexthop ID support for bridge

   - Implement drop reasons support in openvswitch

   - Several data races annotations and fixes

   - Constify the sk parameter of routing functions

   - Prepend kernel version to netconsole message

  Protocols:

   - Implement support for TCP probing the peer being under memory
     pressure

   - Remove hard coded limitation on IPv6 specific info placement inside
     the socket struct

   - Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated per
     socket scaling factor

   - Scaling-up the IPv6 expired route GC via a separated list of
     expiring routes

   - In-kernel support for the TLS alert protocol

   - Better support for UDP reuseport with connected sockets

   - Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
     header size

   - Get rid of additional ancillary per MPTCP connection struct socket

   - Implement support for BPF-based MPTCP packet schedulers

   - Format MPTCP subtests selftests results in TAP

   - Several new SMC 2.1 features including unique experimental options,
     max connections per lgr negotiation, max links per lgr negotiation

  BPF:

   - Multi-buffer support in AF_XDP

   - Add multi uprobe BPF links for attaching multiple uprobes and usdt
     probes, which is significantly faster and saves extra fds

   - Implement an fd-based tc BPF attach API (TCX) and BPF link support
     on top of it

   - Add SO_REUSEPORT support for TC bpf_sk_assign

   - Support new instructions from cpu v4 to simplify the generated code
     and feature completeness, for x86, arm64, riscv64

   - Support defragmenting IPv(4|6) packets in BPF

   - Teach verifier actual bounds of bpf_get_smp_processor_id() and fix
     perf+libbpf issue related to custom section handling

   - Introduce bpf map element count and enable it for all program types

   - Add a BPF hook in sys_socket() to change the protocol ID from
     IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy

   - Introduce bpf_me_mcache_free_rcu() and fix OOM under stress

   - Add uprobe support for the bpf_get_func_ip helper

   - Check skb ownership against full socket

   - Support for up to 12 arguments in BPF trampoline

   - Extend link_info for kprobe_multi and perf_event links

  Netfilter:

   - Speed-up process exit by aborting ruleset validation if a fatal
     signal is pending

   - Allow NLA_POLICY_MASK to be used with BE16/BE32 types

  Driver API:

   - Page pool optimizations, to improve data locality and cache usage

   - Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the
     need for raw ioctl() handling in drivers

   - Simplify genetlink dump operations (doit/dumpit) providing them the
     common information already populated in struct genl_info

   - Extend and use the yaml devlink specs to [re]generate the split ops

   - Introduce devlink selective dumps, to allow SF filtering SF based
     on handle and other attributes

   - Add yaml netlink spec for netlink-raw families, allow route, link
     and address related queries via the ynl tool

   - Remove phylink legacy mode support

   - Support offload LED blinking to phy

   - Add devlink port function attributes for IPsec
