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.

treewide: replace AUTORELEASE with real PKG_RELEASE Based on Paul Fertser <fercerpav@gmail.com>'s guidance: Change AUTORELEASE in rules.mk to: ``` AUTORELEASE = $(if $(DUMP),0,$(shell sed -i "s/\$$(AUTORELEASE)/$(call commitcount,1)/" $(CURDIR)/Makefile)) ``` then update all affected packages by: ``` for i in $(git grep -l PKG_RELEASE:=.*AUTORELEASE | sed 's^.*/\([^/]*\)/Makefile^\1^';); do make package/$i/clean done ``` Signed-off-by: Tianling Shen <cnsztl@immortalwrt.org>

This driver is responsible for sending error reports to the vectoring
control entity, which is required for downstream vectoring to work.
The error reports are generated by the DSL firmware, and passed to this
driver by the MEI driver.

kernel: Make use of KERNEL_MAKE Make use of KERNEL_MAKE in kernel packages were easily possible. This moves some more code to common places and reduces the number of lines. It is defined like this: KERNEL_MAKE = $(MAKE) $(KERNEL_MAKEOPTS) KERNEL_MAKEOPTS = -C $(LINUX_DIR) $(KERNEL_MAKE_FLAGS) Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
