Pull networking updates from Jakub Kicinski:
 "The zero-copy changes are relatively significant, but regression risk
  should be contained. The feature needs to be used to cause trouble.

  Also it feels like we got an order of magnitude more semi-automated
  "refactoring" chaff than usual, I wonder if it's just us.

  Core & protocols:

   - Support Device Memory TCP, ability to zero-copy receive TCP
     payloads to a DMABUF region of memory while packet headers land
     separately in normal kernel buffers, and TCP processes then as
     usual.

   - The ability to read the PTP PHC (Physical Hardware Clock) alongside
     MONOTONIC_RAW timestamps with PTP_SYS_OFFSET_EXTENDED. Previously
     only CLOCK_REALTIME was supported.

   - Allow matching on all bits of IP DSCP for routing decisions.
     Previously we only supported on matching TOS bits in IPv4 which is
     a narrower interpretation of the same header field.

   - Increase the range of weights used for multi-path routing from
     8 bits to 16 bits.

   - Add support for IPv6 PIO p flag in the Prefix Information Option
     per draft-ietf-6man-pio-pflag.

   - IPv6 IOAM6 support for new tunsrc encap mode for better
     performance.

   - Detect destinations which blackhole MPTCP traffic and avoid
     initiating MPTCP connections to them for a certain period of time,
     1h by default.

   - Improve IPsec control path performance by removing the inexact
     policies list.

   - AF_VSOCK: add support for SIOCOUTQ ioctl.

   - Add enum for reasons TCP reset was sent for easier tracing.

   - Add SMC ringbufs usage statistics.

  Drivers:

   - Handle netconsole setup failures more gracefully, don't fail
     loading, retain the specified target as disabled.

   - Extend bonding's IPsec offload pass thru capabilities (ESN, stats).

  Filtering:

   - Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case
     when long-lived sockets miss a chance to set additional callbacks
     if a sockops program was not attached early in their lifetime.

   - Support using BPF skb helpers in tracepoints.

   - Conntrack Netlink: support CTA_FILTER for flush.

   - Improve SCTP support in nfnetlink_queue.

   - Improve performance of large nftables flush transactions.

  Things we sprinkled into general kernel code:

   - selftests: support setting an "interpreter" for script files; make
     it easy to run as separate cases tests where one "interpreter" is
     fed various test descriptions (in our case packet sequences).

  Driver API:

   - Extend core and ethtool APIs to support many PHYs connected to a
     single interface (PHY topologies).

   - Extend cable diagnostics to specify whether Time Domain
     Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was
     used.

   - Add library for implementing MAC-PHY Ethernet drivers for SPI
     devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial
     Interface (TC6) standard.

   - Add helpers to the PHY framework, for PHYs following the Open
     Alliance standards:
       - 1000BaseT1 link settings
       - cable test and diagnostics

   - Support listing / dumping all allocated RSS contexts.

   - Add configuration for frequency Embedded SYNC in DPLL, which
     magically embeds sync pulses into Ethernet signaling.
