Merge tag 'net-6.18-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
  Including fixes from bluetooth and wireless.

  Current release - new code bugs:

   - ptp: expose raw cycles only for clocks with free-running counter

   - bonding: fix null-deref in actor_port_prio setting

   - mdio: ERR_PTR-check regmap pointer returned by
     device_node_to_regmap()

   - eth: libie: depend on DEBUG_FS when building LIBIE_FWLOG

  Previous releases - regressions:

   - virtio_net: fix perf regression due to bad alignment of
     virtio_net_hdr_v1_hash

   - Revert "wifi: ath10k: avoid unnecessary wait for service ready
     message" caused regressions for QCA988x and QCA9984

   - Revert "wifi: ath12k: Fix missing station power save configuration"
     caused regressions for WCN7850

   - eth: bnxt_en: shutdown FW DMA in bnxt_shutdown(), fix memory
     corruptions after kexec

  Previous releases - always broken:

   - virtio-net: fix received packet length check for big packets

   - sctp: fix races in socket diag handling

   - wifi: add an hrtimer-based delayed work item to avoid low
     granularity of timers set relatively far in the future, and use it
     where it matters (e.g. when performing AP-scheduled channel switch)

   - eth: mlx5e:
       - correctly propagate error in case of module EEPROM read failure
       - fix HW-GRO on systems with PAGE_SIZE == 64kB

   - dsa: b53: fixes for tagging, link configuration / RMII, FDB,
     multicast

   - phy: lan8842: implement latest errata"
