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

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2025-11-06 (i40, ice, iavf)

Mohammad Heib introduces a new devlink parameter, max_mac_per_vf, for
controlling the maximum number of MAC address filters allowed by a VF. This
allows administrators to control the VF behavior in a more nuanced manner.

Aleksandr and Przemek add support for Receive Side Scaling of GTP to iAVF
for VFs running on E800 series ice hardware. This improves performance and
scalability for virtualized network functions in 5G and LTE deployments.

* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  iavf: add RSS support for GTP protocol via ethtool
  ice: Extend PTYPE bitmap coverage for GTP encapsulated flows
  ice: improve TCAM priority handling for RSS profiles
  ice: implement GTP RSS context tracking and configuration
  ice: add virtchnl definitions and static data for GTP RSS
  ice: add flow parsing for GTP and new protocol field support
  i40e: support generic devlink param "max_mac_per_vf"
  devlink: Add new "max_mac_per_vf" generic device param
====================
