Merge tag 'net-6.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from can, bpf and netfilter.

  There are a bunch of regressions addressed here, but hopefully nothing
  spectacular. We are still waiting the driver fix from Intel, mentioned
  by Jakub in the previous networking pull.

  Current release - regressions:

   - core: add softirq safety to netdev_rename_lock

   - tcp: fix tcp_rcv_fastopen_synack() to enter TCP_CA_Loss for failed
     TFO

   - batman-adv: fix RCU race at module unload time

  Previous releases - regressions:

   - openvswitch: get related ct labels from its master if it is not
     confirmed

   - eth: bonding: fix incorrect software timestamping report

   - eth: mlxsw: fix memory corruptions on spectrum-4 systems

   - eth: ionic: use dev_consume_skb_any outside of napi

  Previous releases - always broken:

   - netfilter: fully validate NFT_DATA_VALUE on store to data registers

   - unix: several fixes for OoB data

   - tcp: fix race for duplicate reqsk on identical SYN

   - bpf:
       - fix may_goto with negative offset
       - fix the corner case with may_goto and jump to the 1st insn
       - fix overrunning reservations in ringbuf

   - can:
       - j1939: recover socket queue on CAN bus error during BAM
         transmission
       - mcp251xfd: fix infinite loop when xmit fails

   - dsa: microchip: monitor potential faults in half-duplex mode

   - eth: vxlan: pull inner IP header in vxlan_xmit_one()

   - eth: ionic: fix kernel panic due to multi-buffer handling

  Misc:

   - selftest: unix tests refactor and a lot of new cases added"
