- Process the list of local IPs once instead of once per adapter. Add addresses from all VNETs to the driver's list but leave hardware updates for later when the global VNET/IFADDR list locks have been released. - Add address to the hardware table synchronously when a CLIP entry is requested for an address that's not already in there. - Provide ioctls that allow userspace tools to manage addresses in the CLIP table. - Add a knob (hw.cxgbe.clip_db_auto) that controls whether local IPs are automatically added to the CLIP table or not.
