Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2025-06-09 (ice, i40e, ixgbe, iavf)

Jake moves from individual virtchnl RSS configuration values, for ice,
i40e, and iavf, to a common libie location and values.

Martyna and Dawid add counters for link_down_events to ice, i40e, and
ixgbe drivers. The counter increments only on actual physical link-down
events visible to the PHY. It does not increment when the user performs
a software-only interface down/up (e.g. ip link set dev down).

The counter does increment in cases where the interface is reinitialized
in a way that causes a real link drop - such as eg. when attaching
an XDP program, reconfiguring channels, or toggling certain priv-flags.

For ice:
Arkadiusz and Karol separate PTP and DPLL functionality to their
respective APIs.

Michal adds a separate handler for Flow Director command processing.

For iavf:
Ahmed converts driver to utilize core's IRQ affinity API.

For ixgbe:
Alok Tiwari fixes issues with some comments; typos, copy/paste errors,
etc.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ixgbe: Fix typos and clarify comments in X550 driver code
  iavf: convert to NAPI IRQ affinity API
  ice: add a separate Rx handler for flow director commands
  ice: add ice driver PTP pin documentation
  ice: change SMA pins to SDP in PTP API
  ice: redesign dpll sma/u.fl pins control
  ixgbe: add link_down_events statistic
  i40e: add link_down_events statistic
  ice: add link_down_events statistic
  net: intel: move RSS packet classifier types to libie
  net: intel: rename 'hena' to 'hashcfg' for clarity
