Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2024-07-11 (net/intel)

This series contains updates to most Intel network drivers.

Tony removes MODULE_AUTHOR from drivers containing the entry.

Simon Horman corrects a kdoc entry for i40e.

Pawel adds implementation for devlink param "local_forwarding" on ice.

Michal removes unneeded call, and code, for eswitch rebuild for ice.

Sasha removed a no longer used field from igc.

* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  igc: Remove the internal 'eee_advert' field
  ice: remove eswitch rebuild
  ice: Add support for devlink local_forwarding param
  i40e: correct i40e_addr_to_hkey() name in kdoc
  net: intel: Remove MODULE_AUTHORs

+      - runtime
+      - Controls loopback behavior by tuning scheduler bandwidth.
+        It impacts all kinds of functions: physical, virtual and
+        subfunctions.
+        Supported values are:
+
+        ``enabled`` - loopback traffic is allowed on port
+
+        ``disabled`` - loopback traffic is not allowed on this port
+
+        ``prioritized`` - loopback traffic is prioritized on this port
+
+        Default value of ``local_forwarding`` parameter is ``enabled``.
+        ``prioritized`` provides ability to adjust loopback traffic rate to increase
+        one port capacity at cost of the another. User needs to disable
+        local forwarding on one of the ports in order have increased capacity
+        on the ``prioritized`` port.
