The netiucv driver creates TCP/IP interfaces over IUCV between Linux guests on z/VM and other z/VM entities. Rationale for removal: - NETIUCV connections are only supported for compatibility with earlier versions and not to be used for new network setups, since at least Linux kernel 4.0. - No known active users, use cases, or product dependencies - The driver is no longer relevant for z/VM networking; preferred methods include: * Device pass-through (e.g., OSA, RoCE) * z/VM Virtual Switch (VSWITCH) The IUCV mechanism itself remains supported and is actively used via AF_IUCV, hvc_iucv, and smsg_iucv.
