Merge tag 'net-6.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from BPF and netfilter.

  Current release - regressions:

   - core: fix undefined behavior in netdev name allocation

   - bpf: do not allocate percpu memory at init stage

   - netfilter: nf_tables: split async and sync catchall in two
     functions

   - mptcp: fix possible NULL pointer dereference on close

  Current release - new code bugs:

   - eth: ice: dpll: fix initial lock status of dpll

  Previous releases - regressions:

   - bpf: fix precision backtracking instruction iteration

   - af_unix: fix use-after-free in unix_stream_read_actor()

   - tipc: fix kernel-infoleak due to uninitialized TLV value

   - eth: bonding: stop the device in bond_setup_by_slave()

   - eth: mlx5:
      - fix double free of encap_header
      - avoid referencing skb after free-ing in drop path

   - eth: hns3: fix VF reset

   - eth: mvneta: fix calls to page_pool_get_stats

  Previous releases - always broken:

   - core: set SOCK_RCU_FREE before inserting socket into hashtable

   - bpf: fix control-flow graph checking in privileged mode

   - eth: ppp: limit MRU to 64K

   - eth: stmmac: avoid rx queue overrun

   - eth: icssg-prueth: fix error cleanup on failing initialization

   - eth: hns3: fix out-of-bounds access may occur when coalesce info is
     read via debugfs

   - eth: cortina: handle large frames

  Misc:

   - selftests: gso: support CONFIG_MAX_SKB_FRAGS up to 45"
