[PATCH v3 0/6] add ubus support to ltq-[v|a]dsl-app

[Andre Heider]

v3:
- copy dsl_cpe_ubus.c from ltq-adsl-app to ltq-vdsl-app instead of using
  a symlink
- squash PKG_RELEASE patches
- move feed patches to PRs:
  https://github.com/openwrt/packages/pull/14572
  https://github.com/openwrt/luci/pull/4749

v2:
- drop 0002-ltq-vdsl-app-fix-Wundef-warnings.patch
- use "/dev/dsl_cpe_api" without the "0" suffix for the adsl daemon:
  package/kernel/lantiq/ltq-adsl/patches/100-dsl_compat.patch:+   device_create(dsl_class, NULL, MKDEV(DRV_DSL_CPE_API_DEV_MAJOR, 0), NULL, "dsl_cpe_api");
  package/kernel/lantiq/ltq-vdsl/patches/100-compat.patch:+   device_create(dsl_class, NULL, dsl_devt, NULL, "dsl_cpe_api0");
- use callDSLMetrics() for luci, per jo
- add Tested-by tags

This is to significantly speed up the generation of the metrics.

The motivation comes from the fact that ~2.6s is just way too
ineffcient for interval based metric collectors like prometheus or
collectd.

The luci status page also loads/refreshes alot faster.

$ time /etc/init.d/dsl_control dslstat
real	0m 2.66s
user	0m 0.90s
sys	0m 1.76s

$ time ubus call dsl metrics
real	0m 0.02s
user	0m 0.00s
sys	0m 0.01s

The ltq-adsl-app changes are only compile time tested.
