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

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2024-04-01 (ice)

This series contains updates to ice driver only.

Michal Schmidt changes flow for gettimex64 to use host-side spinlock
rather than hardware semaphore for lighter-weight locking.

Steven adds ability for switch recipes to be re-used when firmware
supports it.

Thorsten Blum removes unwanted newlines in netlink messaging.

Michal Swiatkowski and Piotr re-organize devlink related code; renaming,
moving, and consolidating it to a single location. Michal also
simplifies the devlink init and cleanup path to occur under a single
lock call.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ice: hold devlink lock for whole init/cleanup
  ice: move devlink port code to a separate file
  ice: move ice_devlink.[ch] to devlink folder
  ice: Remove newlines in NL_SET_ERR_MSG_MOD
  ice: Add switch recipe reusing feature
  ice: fold ice_ptp_read_time into ice_ptp_gettimex64
  ice: avoid the PTP hardware semaphore in gettimex64 path
  ice: add ice_adapter for shared data across PFs on the same NIC
