Merge tag 'net-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from wireless and netfilter.

  The notable fixes here are the EEE fix which restores boot for many
  embedded platforms (real and QEMU); WiFi warning suppression and the
  ICE Kconfig cleanup.

  Current release - regressions:

   - phy: multiple fixes for EEE rework

   - wifi: wext: warn about usage only once

   - wifi: ath11k: allow system suspend to survive ath11k

  Current release - new code bugs:

   - mlx5: Fix memory leak in IPsec RoCE creation

   - ibmvnic: assign XPS map to correct queue index

  Previous releases - regressions:

   - netfilter: ip6t_rpfilter: Fix regression with VRF interfaces

   - netfilter: ctnetlink: make event listener tracking global

   - nf_tables: allow to fetch set elements when table has an owner

   - mlx5:
      - fix skb leak while fifo resync and push
      - fix possible ptp queue fifo use-after-free

  Previous releases - always broken:

   - sched: fix action bind logic

   - ptp: vclock: use mutex to fix "sleep on atomic" bug if driver also
     uses a mutex

   - netfilter: conntrack: fix rmmod double-free race

   - netfilter: xt_length: use skb len to match in length_mt6, avoid
     issues with BIG TCP

  Misc:

   - ice: remove unnecessary CONFIG_ICE_GNSS

   - mlx5e: remove hairpin write debugfs files

   - sched: act_api: move TCA_EXT_WARN_MSG to the correct hierarchy"
