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

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2024-03-25 (ice, ixgbe, igc)

This series contains updates to ice, ixgbe, and igc drivers.

Steven fixes incorrect casting of bitmap type for ice driver.

Jesse fixes memory corruption issue with suspend flow on ice.

Przemek adds GFP_ATOMIC flag to avoid sleeping in IRQ context for ixgbe.

Kurt Kanzenbach removes no longer valid comment on igc.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  igc: Remove stale comment about Tx timestamping
  ixgbe: avoid sleeping allocation in ixgbe_ipsec_vf_add_sa()
  ice: fix memory corruption bug with suspend and rebuild
  ice: Refactor FW data type and fix bitmap casting issue
====================
