Pull networking fixes from David Miller:
 "Yeah I should have sent a pull request last week, so there is a lot
  more here than usual:

   1) Fix memory leak in ebtables compat code, from Wenwen Wang.

   2) Several kTLS bug fixes from Jakub Kicinski (circular close on
      disconnect etc.)

   3) Force slave speed check on link state recovery in bonding 802.3ad
      mode, from Thomas Falcon.

   4) Clear RX descriptor bits before assigning buffers to them in
      stmmac, from Jose Abreu.

   5) Several missing of_node_put() calls, mostly wrt. for_each_*() OF
      loops, from Nishka Dasgupta.

   6) Double kfree_skb() in peak_usb can driver, from Stephane Grosjean.

   7) Need to hold sock across skb->destructor invocation, from Cong
      Wang.

   8) IP header length needs to be validated in ipip tunnel xmit, from
      Haishuang Yan.

   9) Use after free in ip6 tunnel driver, also from Haishuang Yan.

  10) Do not use MSI interrupts on r8169 chips before RTL8168d, from
      Heiner Kallweit.

  11) Upon bridge device init failure, we need to delete the local fdb.
      From Nikolay Aleksandrov.

  12) Handle erros from of_get_mac_address() properly in stmmac, from
      Martin Blumenstingl.

  13) Handle concurrent rename vs. dump in netfilter ipset, from Jozsef
      Kadlecsik.

  14) Setting NETIF_F_LLTX on mac80211 causes complete breakage with
      some devices, so revert. From Johannes Berg.

  15) Fix deadlock in rxrpc, from David Howells.

  16) Fix Kconfig deps of enetc driver, we must have PHYLIB. From Yue
      Haibing.

  17) Fix mvpp2 crash on module removal, from Matteo Croce.

  18) Fix race in genphy_update_link, from Heiner Kallweit.

  19) bpf_xdp_adjust_head() stopped working with generic XDP when we
      fixes generic XDP to support stacked devices properly, fix from
      Jesper Dangaard Brouer.

  20) Unbalanced RCU locking in rt6_update_exception_stamp_rt(), from
      David Ahern.

  21) Several memory leaks in new sja1105 driver, from Vladimir Oltean"

@ -424,13 +424,24 @@ Statistics
Following minimum set of TLS-related statistics should be reported
by the driver:
* ``rx_tls_decrypted`` - number of successfully decrypted TLS segments
* ``tx_tls_encrypted`` - number of in-order TLS segments passed to device
for encryption
* ``rx_tls_decrypted_packets`` - number of successfully decrypted RX packets
which were part of a TLS stream.
* ``rx_tls_decrypted_bytes`` - number of TLS payload bytes in RX packets
which were successfully decrypted.
* ``tx_tls_encrypted_packets`` - number of TX packets passed to the device
for encryption of their TLS payload.
* ``tx_tls_encrypted_bytes`` - number of TLS payload bytes in TX packets
passed to the device for encryption.
* ``tx_tls_ctx`` - number of TLS TX HW offload contexts added to device for
encryption.
* ``tx_tls_ooo`` - number of TX packets which were part of a TLS stream
but did not arrive in the expected order
* ``tx_tls_drop_no_sync_data`` - number of TX packets dropped because
they arrived out of order and associated record could not be found
but did not arrive in the expected order.
* ``tx_tls_drop_no_sync_data`` - number of TX packets which were part of
a TLS stream dropped, because they arrived out of order and associated
record could not be found.
* ``tx_tls_drop_bypass_req`` - number of TX packets which were part of a TLS
stream dropped, because they contain both data that has been encrypted by
software and data that expects hardware crypto offload.
