Provide a mechanism to load a custom KPU (Key Parse Unit) profile directly from the filesystem at module load time. When the rvu_af module is loaded with the kpu_profile parameter, the specified profile is read from /lib/firmware/kpu and programmed into the KPU registers. Add npc_kpu_profile_cam2 for the extended cam format used by filesystem-loaded profiles and support ptype/ptype_mask in npc_config_kpucam when profile->from_fs is set. Usage: 1. Copy the KPU profile file to /lib/firmware/kpu. 2. Build OCTEONTX2_AF as a module. 3.
