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

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2025-02-10 (ice, igc, e1000e)

For ice:

Karol, Jake, and Michal add PTP support for E830 devices. Karol
refactors and cleans up PTP code. Jake allows for a common
cross-timestamp implementation to be shared for all devices and
Michal adds E830 support.

Mateusz cleans up initial Flow Director rule creation to loop rather
than duplicate repeated similar calls.

For igc:

Siang adjust calls to remove need for close and open calls on loading
XDP program.

For e1000e:

Gerhard Engleder batches register writes for writing multicast table
on real-time kernels.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  e1000e: Fix real-time violations on link up
  igc: Avoid unnecessary link down event in XDP_SETUP_PROG process
  ice: refactor ice_fdir_create_dflt_rules() function
  ice: Implement PTP support for E830 devices
  ice: Refactor ice_ptp_init_tx_*
  ice: Add unified ice_capture_crosststamp
  ice: Process TSYN IRQ in a separate function
  ice: Use FIELD_PREP for timestamp values
  ice: Remove unnecessary ice_is_e8xx() functions
  ice: Don't check device type when checking GNSS presence
