Merge tag 'net-7.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from Netfilter, IPsec, Bluetooth and WiFi.

  Current release - fix to a fix:

   - ipmr: add __rcu to netns_ipv4.mrt, make sure we hold the RCU lock
     in all relevant places

  Current release - new code bugs:

   - fixes for the recently added resizable hash tables

   - ipv6: make sure we default IPv6 tunnel drivers to =m now that IPv6
     itself is built in

   - drv: octeontx2-af: fixes for parser/CAM fixes

  Previous releases - regressions:

   - phy: micrel: fix LAN8814 QSGMII soft reset

   - wifi:
       - cw1200: revert "Fix locking in error paths"
       - ath12k: fix crash on WCN7850, due to adding the same queue
         buffer to a list multiple times

  Previous releases - always broken:

   - number of info leak fixes

   - ipv6: implement limits on extension header parsing

   - wifi: number of fixes for missing bound checks in the drivers

   - Bluetooth: fixes for races and locking issues

   - af_unix:
       - fix an issue between garbage collection and PEEK
       - fix yet another issue with OOB data

   - xfrm: esp: avoid in-place decrypt on shared skb frags

   - netfilter: replace skb_try_make_writable() by skb_ensure_writable()

   - openvswitch: vport: fix race between tunnel creation and linking
     leading to invalid memory accesses (type confusion)

   - drv: amd-xgbe: fix PTP addend overflow causing frozen clock

  Misc:

   - sched/isolation: make HK_TYPE_KTHREAD an alias of HK_TYPE_DOMAIN
     (for relevant IPVS change)"
