d4ce91749d ltq-vdsl-app: add error vector counters to the ubus metrics
These are useful stats to debug vector related line deteriorations,
see [0].

Example output:
    "erb": {
	    "sent": 169925,
	    "discarded": 0
    }

cde7dd6f78 ltq-vdsl-app: prepare for multiple mei ioctls
Refactor so that the outer function opens and closes the mei fd and
passes it around, just as with the main fd.

That also allows us to use the IOCTL macro in get_vector_status() and
clean up accordingly.

Switch to AUTORELEASE while at it.

50cce31561 ltq-vdsl/ltq-vdsl-app: clean up configure args
The userspace application now uses the model=full option to match the
configuration of the kernel module. The source no longer contains SOAP
support, which was the primary reason to build only typical instead
of full before.

This makes several CLI commands, which were already supported in the
kernel module, available in the userspace application. For example, this
includes bbsg which allows to get information about VDSL2 bands.

Some previously applied build options were redundant. Disabling ADSL MIB
support is unnecessary, as it only applies to Danube. ADSL LED support
is no longer included in the source. ReTx counters are already included
with model type full.

This increases the size of the userspace application by approximately
15 kB (uncompressed). The kernel module does not change at all.

7f030c9912 ltq-vdsl-app: extent dsl metrics with state_num and power_state_num
With the old ubus dsl API, the numbers for the individual line_states and
power_states were also returned. These were not ported to the new DSL
C-API. This commit adds the missing information.

For this the internal values are mapped to numbers.

* additional JSON output for state_num:
"state_num": <map_state_number>

Since not all values are meaningful only the following values are
implemented, this can be extended if the future.

* LSTATE_MAP_NOT_INITIALIZED
* LSTATE_MAP_EXCEPTION
* LSTATE_MAP_IDLE
* LSTATE_MAP_SILENT
* LSTATE_MAP_HANDSHAKE
* LSTATE_MAP_FULL_INIT
* LSTATE_MAP_SHOWTIME_NO_SYNC
* LSTATE_MAP_SHOWTIME_TC_SYNC
* LSTATE_MAP_RESYNC

* additinal JSON output for power_level:
"power_state_num": <map_power_satte_number>,

Since there are not so many here, all are mapped.

* PSTATE_MAP_NA,
* PSTATE_MAP_L0,
* PSTATE_MAP_L1,
* PSTATE_MAP_L2,
* PSTATE_MAP_L3,

76dad6eae5 lantiq: use ActualNetDataRate for speed reporting
Switch to Actual Net Data Rate (ACTNDR) for speed reporting on lantiq VDSL modems

Refer to ITU-T G.997.1 chapter 7.5.2.8

Independent whether retransmission is used or not in a given transmit direction:
-   In L0 state, this parameter reports the Net Data Rate (as specified in G.992.3, G.992.5 or G.993.2) at which the bearer channel is operating.
-   In  L2 state, the parameter contains the Net Data Rate (as specified in G.992.3, G.992.5 or G.993.2) in the previous L0 state.

786e7386e0 ltq-vdsl-app: fix -Wundef warnings
The following warnings are shown during build:

/usr/include/vdsl/cmv_message_format.h:33:6: warning: "MEI_SUPPORT_DEBUG_STREAMS" is not defined, evaluates to 0 [-Wundef]
 #if (MEI_SUPPORT_DEBUG_STREAMS == 1)
      ^~~~~~~~~~~~~~~~~~~~~~~~~
/usr/include/vdsl/drv_mei_cpe_interface.h:2256:6: warning: "MEI_SUPPORT_OPTIMIZED_FW_DL" is not defined, evaluates to 0 [-Wundef]
 #if (MEI_SUPPORT_OPTIMIZED_FW_DL == 1)
      ^~~~~~~~~~~~~~~~~~~~~~~~~~~

The headers are provided by the MEI driver, but the defines are never
set by the vdsl app. While the struct with the
MEI_SUPPORT_OPTIMIZED_FW_DL conditional isn't used by the vdsl app,
however CMV_USED_PAYLOAD_8BIT_SIZE which value depends on
MEI_SUPPORT_DEBUG_STREAMS is.

Since the MEI driver doesn't provide an autogenerated header with
compile flags, the flags are hardcoded for the vdsl app.

Set them for the MEI driver as well, to indicate a relation to the
values used for the vdsl app and to be not surprised by a changed
default in case the MEI driver gets updated. Use the current default
values defined in the MEI driver.

f9b2da255d ltq-vdsl-app: shutdown upon sigterm
procd sends sigterm to stop daemons, hook it up.

This speeds up the shutdown sequence and gets rid of the following message:
daemon.info procd: Instance dsl_control::instance1 pid 15408 not stopped on SIGTERM, sending SIGKILL instead

0bc6a69776 treewide: unify OpenWrt hosted source via @OPENWRT
Multiple sources are hosted on OpenWrts source server only. The source
URLs to point to the server vary based on different epochs in OpenWrts
history.

Replace all by @OPENWRT which is an "empty" mirror, therefore using the
fallback servers sources.cdn.openwrt.org and sources.openwrt.org.

vxlan: allow for dynamic source ip selection (FS#3426)
By setting 'auto', the zero address or the empty string as source
address (option ipaddr, option ip6addr), vxlan will choose one
dynamically. This helps in setups where a wan ip or prefix changes.

This corresponse to setting up an vxlan tunnel with:

proto vxlan6:
    # ip link add vx0 type vxlan id ID local :: ...
proto vxlan:
    # ip link add vx0 type vxlan id ID local 0.0.0.0 ...

While it is possible to not specify a source ip at all, the kernel will
default to setting up a ipv4 tunnel. The kernel will take any hint from
source and peer ips to figure out, what tunnel type to use. To make sure
we setup an ipv6 tunnel for proto vxlan6, this workaround is needed.

This will not change the behaviour of currently working configurations.
However this will allow former broken configurations, namely those not
specifying both a source address and tunnel interface, to setup a
tunnel interface. Previously those configurations weren't reporting an
error and were stueck in a setup loop like in Bug FS#3426.

This change lifts the currently very strict behaviour and should fix the
following bug:

2538759688 xfrm: support 'multicast' attribute on interfaces
You shouldn't need the overhead of GRE just to add multicast
capability on a point-to-point interface (for instance, you might
want to run mDNS over IPsec transport connections, and Avahi
requires IFF_MULTICAST be set on interfaces, even point-to-point
ones).

Borrowed heavily from:
