Update iproute2 to latest stable version, see https://lwn.net/Articles/805654/

Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
* wg-quick: linux: suppress error when finding unused table
This fixes a spurious warning messages seen with recent versions of iproute2
and kernels.
* wg-quick: linux: ensure postdown hooks execute
* wg-quick: linux: have remove_iptables return true
* wg-quick: linux: iptables-* -w is not widely supported
Adding in iptables had some hiccups. For the record, I'm very unhappy about
having to put any firewalling code into wg-quick(8). We'll of course need to
support nftables too at some point if this continues. I'm investigating with
upstream the possibility of adding a sysctl to patch the issue that iptables
is handling now, so hopefully at somepoint down the line we'll be able to shed
this dependency once again.
* send: use kfree_skb_list
* device: prepare skb_list_walk_safe for upstreaming
* send: avoid touching skb->{next,prev} directly

In d421a8b944 ("ath79: read label MAC address from flash instead
of using phy0/phy1") the source of the label MAC address was changed
for devices just reading it from phy0. To get rid of the dependency
from phy startup, addresses were read directly from the flash
locations that are used to initialize the phy MAC addresses.
Unfortunately, it turned out that Ubiquiti XM devices seem to have
different flash locations than expected, and also seem to have
specific locations for different devices (all in art/EEPROM):
0xe012 AR9280 Nanostation M2 - 0x120c
0xe035 AR9280 Nanostation M3 - 0x120c
0xe1b2 AR9280 Rocket M2 - 0x120c
0xe1c3 AR9280 Rocket M3 - 0x120c
0xe1b5 AR9280 Rocket M5 - 0x120c
0xe2d5 AR9280 Bullet M2 Titanium - 0x120c
0xe2b5 AR9280 Nanobridge M5 - 0x120c
0xe202 AR9280 Bullet M2 - 0x120c
0xe232 AR9287 Nanobridge M2 - 0x110c
0xe4a2 AR9285 AirRouter - 0xa0bf
Picostation M2 - 0x120c and 0xa0bf
Nanostation Loco M2 - not in 0x120c, other locations not checked
An additional problem of the Ubiquiti device support in OpenWrt is
that we provide images that match several subvariants of the devices,
which might have different MAC address locations.
Given that reading the address from phy0 in 02_network _is_ working
for the ath79 target in general, it does not seem reasonable to
rebuild a complex MAC address retrieval mechanism which is already
present in the ath9k driver.
So, this patch reverts the label MAC address source for Ubiquiti XM
devices (and the Unifi AP) to /sys/class/ieee80211/phy0/macaddress.
This doesn't affect XW and Unifi AC devices, where the label MAC
address source is defined via device tree.
For alfa-network,ap121f the location 0x1002 is kept, as this has
been verified during device support preparation in PR #2199.

Currently, there's a hard limit of 128 VLANs, which is the same as

MeshPoint.One is Wi-Fi hotspot and smart IoT gateway (based upon
Jalapeno module from 8Devices).
MeshPoint.One (https://meshpointone.com) is a unique Wi-Fi hotspot and
smart city gateway that can be installed and powered from street
lighting (even solar power in the future). MeshPoint provides up to 27
hours of interrupted Wi-Fi and IoT services from internal battery even
when external power is not available. MeshPoint.One can be used for
disaster relief efforts in order to provide instant Wi-Fi coverage that
can be easily expanded by just adding more devices that create wide area
mesh network. MeshPoint.One devices have standard Luci UI for
management.
Features:
- 1x 1Gpbs WAN
- 1x 1Gbps LAN
- POE input (eth0)
- POE output (eth1)
- Sensor for temperature, humidity and pressure (Bosch BME280)
- current, voltage and power measurement via TI INA230
- Hardware real time clock
- optional power via Li-Ion battery
- micro USB port with USB to serial chip for easy OpenWrt terminal
access
- I2C header for connecting additional sensors
Installation:
-------------
Simply flash the sysupgrade image from stock firmware.
Or use the built in Web recovery into bootloader:
Hold Reset button for 5 to 20 seconds or use UART and httpd command.
Web UI will appear on 192.168.2.100 by default.
For web recovery use the factory.ubi image.

This patch is based on #1689 and adds support for TP-Link Archer
C6 v2 (US) and A6 (US/TW).
The hardware is the same as EU and RU variant, except for GPIOs
(LEDS/Buttons), flash(chip/partitions) and UART being available
on the board.
- SOC: Qualcomm QCA9563 @ 775MHz
- Flash: GigaDevice GD25Q127CS1G (16MiB)
- RAM: Zentel A3R1GE40JBF (128 MiB DDR2)
- Ethernet: Qualcomm QCA8337N: 4x 1Gbps LAN + 1x 1Gbps WAN
- Wireless:
- 2.4GHz (bgn) QCA9563 integrated (3x3)
- 5GHz (ac) Qualcomm QCA9886 (2x2)
- Button: 1x power, 1x reset, 1x wps
- LED: 6x LEDs: power, wlan2g, wlan5g, lan, wan, wps
- UART: 115200, 8n1 (header available on board)
Known issues:
- Wireless: 5GHz is known to have lower RSSI signal, it affects speed and range.
Flash instructions:
Upload openwrt-ath79-generic-tplink_archer-c6-v2-us-squashfs-factory.bin
via the router Web interface.
Flash instruction using tftp recovery:
1. Connect the computer to one of the LAN ports of the router
2. Set the computer IP to 192.168.0.66
3. Start a tftp server with the OpenWrt factory image in the
tftp root directory renamed to ArcherA6v2_tp_recovery.bin.
4. Connect power cable to router, press and hold the
reset button and turn the router on
5. Keep the reset button pressed until the WPS LED lights up
6. Wait ~150 seconds to complete flashing
Flash partitioning: I've followed #1689 for defining the partition layout
for this patch. The partition named as "tplink" @ 0xfd0000 is marked
as read only as it is where some config for stock firmware are stored.
On stock firmware those stock partitions starts at 0xfd9400 however
I had not been able to make it functional starting on the same address as
on stock fw, so it has been partitioned following #1689 and not the stock
partition layout for this specific partition. Due to that firmware/rootfs
partition lenght is 0xf80000 and not 0xf89400 as stock.
According to the GPL code, the EU/RU/JP variant does have different GPIO pins
assignment to LEDs and buttons, also the flash memory layout is different.

YunCore XD4200 ('XD4200_W6.0' marking on PCB) is Qualcomm/Atheros based
(QCA9563, QCA9886, QCA8334) dual-band, Wave-2 AC1200 ceiling AP with PoE
(802.3at) support. A782 model ('T750_V5.1' marking on PCB) is a smaller
version of the XD4200, with similar specification but lower TX power.
Specification:
- QCA9563 (775 MHz)
- 128 MB of RAM (DDR2)
- 16 MB of FLASH (SPI NOR)
- 2x 10/100/1000 Mbps Ethernet (QCA8334), with 802.3at PoE support (WAN)
- Wi-Fi 2.4 GHz:
- XD4200: 2T2R (QCA9563), with ext. PA (SKY65174-21) and LNA
- A782: 2T2R (QCA9563), with ext. FEM (SKY85329-11)
- Wi-Fi 5 GHz:
- XD4200: 2T2R (QCA9886), with ext. FEM (SKY85728-11)
- A782: 2T2R (QCA9886), with ext. FEM (SKY85735-11)
- LEDs:
- XD4200: 5x (2x driven by SOC, 1x driven by AC radio, 2x Ethernet)
- A782: 3x (1x RGB, driven by SOC and radio, 2x Ethernet)
- 1x button (reset)
- 1x UART (4-pin, 2.54 mm pitch) header on PCB
- 1x DC jack (12 V)
Flash instructions:
If your device comes with generic QSDK based firmware, you can login
over telnet (login: root, empty password, default IP: 192.168.188.253),
issue first (important!) 'fw_setenv' command and then perform regular
upgrade, using 'sysupgrade -n -F ...' (you can use 'wget' to download
image to the device, SSH server is not available):
fw_setenv bootcmd "bootm 0x9f050000 || bootm 0x9fe80000"
sysupgrade -n -F openwrt-...-yuncore_...-squashfs-sysupgrade.bin
In case your device runs firmware with YunCore custom GUI, you can use
U-Boot recovery mode:
1. Set a static IP 192.168.0.141/24 on PC and start TFTP server with
'tftp' image renamed to 'upgrade.bin'
2. Power the device with reset button pressed and release it after 5-7
seconds, recovery mode should start downloading image from server
(unfortunately, there is no visible indication that recovery got
enabled - in case of problems check TFTP server logs)

YunCore QCA9k based devices released in 2019 require a custom TFTP image
for U-Boot built-in recovery mode (triggered with reset button). Image
has to be prepended with 'YUNCORE' keyword followed by U-Boot CLI
commands which will be executed later. Images without the custom header
will be ignored by U-Boot.
To be able to support both the vendor firmware (QSDK) and OpenWrt flash
layouts, used here commands change the 'bootcmd' before flashing image.
This commit adds generic helper script for YunCore devices with 16 MB of
flash and enables TFTP image generation for A770 model.

Sometimes it is desirable to change the downloaded archive file name, like
