Merge tag 'net-5.19-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:

   - eth: amt: fix possible null-ptr-deref in amt_rcv()

  Previous releases - regressions:

   - tcp: use alloc_large_system_hash() to allocate table_perturb

   - af_unix: fix a data-race in unix_dgram_peer_wake_me()

   - nfc: st21nfca: fix memory leaks in EVT_TRANSACTION handling

   - eth: ixgbe: fix unexpected VLAN rx in promisc mode on VF

  Previous releases - always broken:

   - ipv6: fix signed integer overflow in __ip6_append_data

   - netfilter:
       - nat: really support inet nat without l3 address
       - nf_tables: memleak flow rule from commit path

   - bpf: fix calling global functions from BPF_PROG_TYPE_EXT programs

   - openvswitch: fix misuse of the cached connection on tuple changes

   - nfc: nfcmrvl: fix memory leak in nfcmrvl_play_deferred

   - eth: altera: fix refcount leak in altera_tse_mdio_create

  Misc:

   - add Quentin Monnet to bpftool maintainers"
