Merge branch '10GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2025-07-03

Vladimir Oltean converts Intel drivers (ice, igc, igb, ixgbe, i40e) to
utilize new timestamping API (ndo_hwtstamp_get() and ndo_hwtstamp_set()).

For ixgbe:
Paul, Don, Slawomir, and Radoslaw add Malicious Driver Detection (MDD)
support for X550 and E610 devices to detect, report, and handle
potentially malicious VFs.

Simon Horman corrects spelling mistakes.

For igbvf:
Kohei Enju removes a couple of unreported counters and adds reporting
of Tx timeouts.

* '10GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  igbvf: add tx_timeout_count to ethtool statistics
  igbvf: remove unused interrupt counter fields from struct igbvf_adapter
  ixgbe: spelling corrections
  ixgbe: turn off MDD while modifying SRRCTL
  ixgbe: add Tx hang detection unhandled MDD
  ixgbe: check for MDD events
  ixgbe: add MDD support
  i40e: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()
  ixgbe: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()
  igb: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()
  igc: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()
  ice: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()
