[PATCH net-next v2 05/12] ice: create flow profile

From: Tony Nguyen <anthony.l.nguyen@intel.com>
Date: 2026-09-17 18:39:41
Subsystem: intel ethernet drivers, networking drivers, the rest · Maintainers: Tony Nguyen, Przemek Kitszel, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

From: Real Valiquette <redacted>

Implement the initial steps for creating an ACL filter to support ntuple
masks. Create a flow profile based on a given mask rule and program it to
the hardware. Though the profile is written to hardware, no actions are
associated with the profile yet.
