Merge tag 'net-6.1-rc3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from 802.15.4 (Zigbee et al).

  Current release - regressions:

   - ipa: fix bugs in the register conversion for IPA v3.1 and v3.5.1

  Current release - new code bugs:

   - mptcp: fix abba deadlock on fastopen

   - eth: stmmac: rk3588: allow multiple gmac controllers in one system

  Previous releases - regressions:

   - ip: rework the fix for dflt addr selection for connected nexthop

   - net: couple more fixes for misinterpreting bits in struct page
     after the signature was added

  Previous releases - always broken:

   - ipv6: ensure sane device mtu in tunnels

   - openvswitch: switch from WARN to pr_warn on a user-triggerable path

   - ethtool: eeprom: fix null-deref on genl_info in dump

   - ieee802154: more return code fixes for corner cases in
     dgram_sendmsg

   - mac802154: fix link-quality-indicator recording

   - eth: mlx5: fixes for IPsec, PTP timestamps, OvS and conntrack
     offload

   - eth: fec: limit register access on i.MX6UL

   - eth: bcm4908_enet: update TX stats after actual transmission

   - can: rcar_canfd: improve IRQ handling for RZ/G2L

  Misc:

   - genetlink: piggy back on the newly added resv_op_start to enforce
     more sanity checks on new commands"
