Pull networking updates from Paolo Abeni:
 "This is slightly smaller than usual, with the most interesting work
  being still around RTNL scope reduction.

  Core:

   - More core refactoring to reduce the RTNL lock contention, including
     preparatory work for the per-network namespace RTNL lock, replacing
     RTNL lock with a per device-one to protect NAPI-related net device
     data and moving synchronize_net() calls outside such lock.

   - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge
     and more specific TCP coverage.

   - Reduce network namespace tear-down time by removing per-subsystems
     synchronize_net() in tipc and sched.

   - Add flow label selector support for fib rules, allowing traffic
     redirection based on such header field.

  Netfilter:

   - Do not remove netdev basechain when last device is gone, allowing
     netdev basechains without devices.

   - Revisit the flowtable teardown strategy, dealing better with fin,
     reset and re-open events.

   - Scale-up IP-vs connection dumping by avoiding linear search on each
     restart.

  Protocols:

   - A significant XDP socket refactor, consolidating and optimizing
     several helpers into the core

   - Better scaling of ICMP rate-limiting, by removing false-sharing in
     inet peers handling.

   - Introduces netlink notifications for multicast IPv4 and IPv6
     address changes.

   - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
     aggregation and fragmentation of the inner IP.

   - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to
     avoid local port exhaustion issues when the average connection
     lifetime is very short.

   - Support updating keys (re-keying) for connections using kernel TLS
     (for TLS 1.3 only).

   - Support ipv4-mapped ipv6 address clients in smc-r v2.

   - Add support for jumbo data packet transmission in RxRPC sockets,
     gluing multiple data packets in a single UDP packet.

   - Support RxRPC RACK-TLP to manage packet loss and retransmission in
     conjunction with the congestion control algorithm.

  Driver API:

   - Introduce a unified and structured interface for reporting PHY
     statistics, exposing consistent data across different H/W via
     ethtool.

   - Make timestamping selectable, allow the user to select the desired
     hwtstamp provider (PHY or MAC) administratively.

   - Add support for configuring a header-data-split threshold (HDS)
     value via ethtool, to deal with partial or buggy H/W
     implementation.

   - Consolidate DSA drivers Energy Efficiency Ethernet support.

   - Add EEE management to phylink, making use of the phylib
     implementation.

   - Add phylib support for in-band capabilities negotiation.

   - Simplify how phylib-enabled mac drivers expose the supported
     interfaces.

  Tests and tooling:

   - Make the YNL tool package-friendly to make it easier to deploy it
     separately from the kernel.

   - Increase TCP selftest coverage importing several packetdrill
     test-cases.

   - Regenerate the ethtool uapi header from the YNL spec, to ease
     maintenance and future development.

   - Add YNL support for decoding the link types used in net self-tests,
     allowing a single build to run both net and drivers/net.

+
+pack() and unpack()
+^^^^^^^^^^^^^^^^^^^
+
+These are const-correct variants of packing(), and eliminate the last "enum
+packing_op op" argument.
+
+Calling pack(...) is equivalent, and preferred, to calling packing(..., PACK).
+
+Calling unpack(...) is equivalent, and preferred, to calling packing(..., UNPACK).
+
+pack_fields() and unpack_fields()
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The library exposes optimized functions for the scenario where there are many
+fields represented in a buffer, and it encourages consumer drivers to avoid
+repetitive calls to pack() and unpack() for each field, but instead use
+pack_fields() and unpack_fields(), which reduces the code footprint.
+
+These APIs use field definitions in arrays of ``struct packed_field_u8`` or
+``struct packed_field_u16``, allowing consumer drivers to minimize the size
+of these arrays according to their custom requirements.
+
+The pack_fields() and unpack_fields() API functions are actually macros which
+automatically select the appropriate function at compile time, based on the
+type of the fields array passed in.
+
+An additional benefit over pack() and unpack() is that sanity checks on the
+field definitions are handled at compile time with ``BUILD_BUG_ON`` rather
+than only when the offending code is executed. These functions return void and
+wrapping them to handle unexpected errors is not necessary.
+
+It is recommended, but not required, that you wrap your packed buffer into a
+structured type with a fixed size. This generally makes it easier for the
+compiler to enforce that the correct size buffer is used.
+
+Here is an example of how to use the fields APIs:
+
+.. code-block:: c
+
+   /* Ordering inside the unpacked structure is flexible and can be different
+    * from the packed buffer. Here, it is optimized to reduce padding.
+    */
+   struct data {
+        u64 field3;
+        u32 field4;
+        u16 field1;
+        u8 field2;
+   };
+
+   #define SIZE 13
+
+   typdef struct __packed { u8 buf[SIZE]; } packed_buf_t;
+
+   static const struct packed_field_u8 fields[] = {
+           PACKED_FIELD(100, 90, struct data, field1),
+           PACKED_FIELD(90, 87, struct data, field2),
+           PACKED_FIELD(86, 30, struct data, field3),
+           PACKED_FIELD(29, 0, struct data, field4),
+   };
+
+   void unpack_your_data(const packed_buf_t *buf, struct data *unpacked)
+   {
+           BUILD_BUG_ON(sizeof(*buf) != SIZE;
+
+           unpack_fields(buf, sizeof(*buf), unpacked, fields,
+                         QUIRK_LITTLE_ENDIAN);
+   }
+
+   void pack_your_data(const struct data *unpacked, packed_buf_t *buf)
+   {
+           BUILD_BUG_ON(sizeof(*buf) != SIZE;
+
+           pack_fields(buf, sizeof(*buf), unpacked, fields,
+                       QUIRK_LITTLE_ENDIAN);
