Pull networking fixes from David Miller:
 "Hopefully the last pull request for this release. Fingers crossed:

   1) Only refcount ESP stats on full sockets, from Martin Willi.

   2) Missing barriers in AF_UNIX, from Al Viro.

   3) RCU protection fixes in ipv6 route code, from Paolo Abeni.

   4) Avoid false positives in untrusted GSO validation, from Willem de
      Bruijn.

   5) Forwarded mesh packets in mac80211 need more tailroom allocated,
      from Felix Fietkau.

   6) Use operstate consistently for linkup in team driver, from George
      Wilkie.

   7) ThunderX bug fixes from Vadim Lomovtsev. Mostly races between VF
      and PF code paths.

   8) Purge ipv6 exceptions during netdevice removal, from Paolo Abeni.

   9) nfp eBPF code gen fixes from Jiong Wang.

  10) bnxt_en firmware timeout fix from Michael Chan.

  11) Use after free in udp/udpv6 error handlers, from Paolo Abeni.

  12) Fix a race in x25_bind triggerable by syzbot, from Eric Dumazet"

- port_fdb_prepare: bridge layer function invoked when the bridge prepares the
installation of a Forwarding Database entry. If the operation is not
supported, this function should return -EOPNOTSUPP to inform the bridge code

this function. See port_fdb_add for this and details.

Switch ID
^^^^^^^^^
The switchdev driver must implement the switchdev op switchdev_port_attr_get
for SWITCHDEV_ATTR_ID_PORT_PARENT_ID for each port netdev, returning the same
physical ID for each port of a switch. The ID must be unique between switches
on the same system. The ID does not need to be unique between switches on
different systems.
The switchdev driver must implement the net_device operation
ndo_get_port_parent_id for each port netdev, returning the same physical ID for
each port of a switch. The ID must be unique between switches on the same
system. The ID does not need to be unique between switches on different
systems.
The switch ID is used to locate ports on a switch and to know if aggregated
ports belong to the same switch.
