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

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2026-01-20 (ice, idpf)

For ice:
Cody Haas breaks dependency of needing both RSS key and LUT for
ice_get_rxfh() as ethtool ioctls do not always supply both.

Paul fixes issues related to devlink reload; adding missing deinit HW
call and moving hwmon exit function to the proper call chain.

For idpf:
Mina Almasry moves a register read call into the time sandwich to ensure
the register is properly flushed.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  idpf: read lower clock bits inside the time sandwich
  ice: fix devlink reload call trace
  ice: add missing ice_deinit_hw() in devlink reinit path
  ice: Fix persistent failure in ice_get_rxfh
