ltq-vectoring: add driver In order to calculate the required pre-distortion for downstream vectoring, the vectoring control entity (VCE) at the carrier office needs error samples from the modem. On Lantiq VR9 modems, error reports are generated by the firmware, but need to be multiplexed into the data stream by the driver on the main processor when L2 encapsulation is selected by the VCE. This driver provides the necessary callback function, which is called by the MEI driver after receiving an error report from the firmware. Originally, it is part of the Lantiq PPA driver, but after a few changes it also works with the PTM driver used in OpenWrt. The direct call to ndo_start_xmit needs to be replaced, as the PTM driver relies on locks from the kernel. Instead dev_queue_xmit is used, which is called from a work queue, as it is not safe to call from an interrupt handler. Additional changes include fixes to support recent kernel versions and a change of the used interface from ptm0 to dsl0.

lantiq/xrx200: move 8M flash devices to a small flash subtarget Images for xrx200 8M flash are either not building due to image size (TD-W8970, TD-W8980) or building such that the available free space in the overlayfs is too little to be useful. To keep images for these devices buildable, move them into a small flash variant of the xrx200 subtarget. As these devices are NOR flash only, remove NAND and UBI references from the kernel config to gain some additional image size reduction. The apparent 8M flash devices Arcadyan VGV7510KW22-brn, Arcadyan VGV7519-brn and Lantiq Easy80920-nor seem to exist in order to create special "factory" installation images for these devices (which actually have larger flash: 16MB for the Arcardyan devices; 64MB for the Lantiq device). As a considerable amount of surgery would appear to be required to the uboot-lantiq package structure to separate the "factory" from the "sysupgrade" device recipes for these devices they remain in the xrx200 target - if factory images aren't now created, 23.05.x factory images should suffice for initial installation.
