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
