Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2025-07-15 (ixgbe, fm10k, i40e, ice)

Arnd Bergmann resolves compile issues with large NR_CPUS for ixgbe, fm10k,
and i40e.

For ice:
Dave adds a NULL check for LAG netdev.

Michal corrects a pointer check in debugfs initialization.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  ice: check correct pointer in fwlog debugfs
  ice: add NULL check in eswitch lag check
  ethernet: intel: fix building with large NR_CPUS
