All callers of the rtl83xx_mc_group_* functions already do the same
check, so these aren't needed.
For rtl83xx_mc_group_alloc, this branch also incorrectly returned 0
instead of a negative value. If the branch wasn't effectively dead code
anyway, this could potentially have caused bugs, as 0 is a valid
multicast group entry index.

The current implementation only works when store and load are called for
the same port without any other calls in between. This is because the
store function only saves a single port number instead of a portmask for
each group. It also doesn't take into account that the allocation of
multicast group entries might change between store/load calls.
As a result, the multicast port mask table gets corrupted. This also
includes the reserved entry for unknown multicast, which gets corrupted
even when no other mdb entries have been added.
Remove the code for storing/loading multicast groups entirely, as the
original commit message doesn't offer a convincing reason why this would
be necessary in the first place.

There shouldn't be any reason to forward all multicast to the CPU. The
original commit message also doesn't provide a reason for this seemingly
unrelated change.
The current implementation of the delete method is also broken, as it
entirely removes any entry when the portmask contains only the CPU port,
even if it was explicitly created.

There doesn't appear to be a reason to do this, as only the last entry
is actually reserved for unknown multicast.
This also fixes two issues:
- As the increment happened after the bounds check, the value of the
actually reserved last entry could be overwritten.
- On deletion of entries, a corresponding decrement was missing,
causing the wrong entry to be marked as free.

The port_vlan_add method may be called while a port is already a member
of that VLAN, so it needs to be able to handle changed flags. Fix it to
properly handle when the PVID or UNTAGGED flag was previously set, but
now no longer is.
To reduce duplication, move PVID configuration to a separate function.

The registers L2_PORT_STATIC_MV_ACT seem to specify the action to take
when the source address of a packet exists as a static fdb entry on
another port. By default the configured action is to drop such packets.
For standalone ports, this behaviour is undesired, as all traffic should
be forwarded to the CPU. So change the action to forward on standalone
ports.
A situation where this issue can occur is when a non-offloaded bond
interface is part of a bridge. In that case, the CPU port will have fdb
entries for devices connected to the bond interface, which are managed
by the assisted learning feature.
For now, this is only implemented for RTL838x/RTL839x, as the available
set of registers differs for the other devices.

All ports are disabled by default, so configure the port isolation masks
and the pm field accordingly in the setup function. When port_enable is
called for a port, the isolation masks will be set up so that traffic
can flow between the port and the CPU.
While at it, change the code to also use the traffic_set method in
rtl83xx_setup, instead of writing to the RTL838x_PORT_ISO_CTRL(i)
registers directly.

Correctly update the isolation mask of the port being configured. The
port_bitmap variable should contain all other bridge members and needs
to be actually removed from the isolation mask instead of added to it.
Also actually remove the port being configured from the pm field of the

configured correctly when they are enabled.

The ZTE MF282 is a LTE router used (exclusively?) by the network operator
"3".
Specifications
==============
SoC: QCA9563 (775MHz)
RAM: 128MiB
Flash: 8MiB SPI-NOR + 128MiB SPI-NAND
LAN: 1x GBit LAN
LTE: ZTE MF270 (Cat4), detected as P685M
WiFi: QCA9880ac + QCA9560bgn
MAC addresses
=============
LAN: from config
WiFi 1: from config
WiFi 2: +1
Installation
============
TFTP installation using UART is preferred. Disassemble the device and
connect serial. Put the initramfs image as openwrt.bin to your TFTP server
and configure a static IP of 192.168.1.100. Load the initramfs image by
typing:
setenv serverip 192.168.1.100
setenv ipaddr 192.168.1.1
tftpboot 0x82000000 openwrt.bin
bootm 0x82000000
From this intiramfs boot you can take a backup of the currently installed
partitions as no vendor firmware is available for download.
Once booted, transfer the sysupgrade image and run sysupgrade.
LTE Modem
=========
The LTE modem is probably the same as in the MF283+, all instructions
apply.
Configuring the connection using modemmanager works properly, the modem
provides three serial ports and a QMI CDC ethernet interface.

Kernel setting CONFIG_IO_URING supports high-performance I/O for file
access and servers, generally for more performant platforms, and adds
~45 KB to kernel sizes. The need for this on less "beefy" devices is
questionable, as is the size cost considering many platforms have kernel
size limits which require tricky repartitioning if outgrown. The size
cost is also large relative to the ~180 KB bump expected between major
OpenWRT kernel releases.
No OpenWrt packages have hard dependencies on this; samba4 and mariadb
can take advantage if available (+KERNEL_IO_URING:liburing) but
otherwise build and work fine.
Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting
in Config-kernel.in (default Y), remove it from those target configs
which unconditionally enable it, and update the defaults to enable it
conditionally only on more powerful 64-bit x86 and arm devices. It may
still be manually enabled as needed for high-performance custom builds.

This commit adds factory.bin image for TP-Link EC330-G5u v1. This allows
to install OpenWrt without connecting a serial cable (UART).
Installation using factory image
--------------------------------
Tested with "3.16.0 0.9.1 v6037.0 Build 191016 Rel.30619nb" TP-Link
firmware.
1. Login to the router web interface (http://192.168.0.1/ by default) and
save running config to "conf.bin" file
2. Open configuration file in any TP-Link config editor (e.g.
https://jahed.github.io/tp-link-config-editor/)
3. Find "DeviceInfo" section and insert a new string "<Description
val="Modem Router`telnetd -p 1023 -l login`" />" according to the
following example:
<DeviceInfo>
...
<Description val="Modem Router`telnetd -p 1023 -l login`" />
...
</DeviceInfo>
4. Save configuration file and upload changed configuration using stock
firmware interface
5. Login using telnet to IP:192.168.0.1 (Username:admin, password:1234)
6. Run "cat /proc/mtd | grep mtd7"
a. If the result is 'mtd7: 03000000 00020000 "rootfs" 03400000',
then install stock firmware using web interface to toggle booted
firmware image from "os1" to "os0"
b. If the result is 'mtd7: 03000000 00020000 "rootfs" 00400000',
then all is ok, go to the next step
7. Set up a tftp server with OpenWrt factory.bin image (IP:192.168.0.100
in this example)
8. Login using telnet to 192.168.0.1
9. Download OpenWrt factory.bin image from the tftp server:
cd /tmp
tftp -g -r factory.bin 192.168.0.100
10. Write OpenWrt factory.bin image:
dd if=/tmp/factory.bin of=/dev/mtdblock1
11. Power cycle the router

The ZyXEL WSM20 aka Multy M1 is a cheap mesh router system by ZyXEL
based on the MT7621 CPU.
Specifications
==============
SoC: MediaTek MT7621AT (880MHz)
RAM: 256MiB
Flash: 128MiB NAND
Wireless: 802.11ax (2x2 MT7915E DBDC)
Ethernet: 4x 10/100/1000 (MT7530)
Button: 1x WPS, 1x Reset, 1x LED On/Off
LED: 7 LEDs (3x white, 2x red, 2x green)
MAC address assignment
======================
The MAC address assignment follows stock: The label MAC address is the LAN
MAC address, the WAN address is read from flash.
The WiFi MAC addresses are set in userspace to label MAC + 1 and label MAC
+ 2.
Installation (web interface)
============================
The device is cloud-managed, but there is a hidden local firmware upgrade
page in the OEM web interface. The device has to be registered in the
cloud in order to be able to access this page.
The system has a dual firmware design, there is no way to tell which
firmware is currently booted. Therefore, an -initramfs version is flashed
first.
1. Log into the OEM web GUI
2. Access the hidden upgrade page by navigating to
https://192.168.212.1/gui/#/main/debug/firmwareupgrade
3. Upload the -initramfs-kernel.bin file and flash it
4. Wait for OpenWrt to boot and log in via SSH
5. Transfer the sysupgrade file via SCP
6. Run sysupgrade to install the image
7. Reboot and enjoy
NB: If the initramfs version was installed in RAS2, the sysupgrade script
sets the boot number to the first partition. A backup has to be performed
manually in case the OEM firwmare should be kept.
Installation (UART method)
==========================
The UART method is more difficult, as the boot loader does not have a
timeout set. A semi-working stock firmware is required to configure it:
1. Attach UART
2. Boot the stock firmware until the message about failsafe mode appears
3. Enter failsafe mode by pressing "f" and "Enter"
4. Type "mount_root"
5. Run "fw_setenv bootmenu_delay 3"
6. Reboot, U-Boot now presents a menu
7. The -initramfs-kernel.bin image can be flashed using the menu
8. Run the regular sysupgrade for a permanent installation
Changing the partition to boot is a bit cumbersome in U-Boot, as there is
no menu to select it. It can only be checked using mstc_bootnum. To change
it, issue the following commands in U-Boot:
nand read 1800000 53c0000 800
mw.b 1800004 1 1
nand erase 53c0000 800
nand write 1800000 53c0000 800
This selects FW1. Replace "mw.b 1800004 1 1" by "mw.b 1800004 2 1" to
change to the second slot.
Back to stock
=============
It is possible to flash back to stock, but a OEM firmware upgrade is
required. ZyXEL does not provide the link on its website, but the link
can be acquired from the OEM web GUI by analyzing the transferred JSON
objects.
It is then a matter of writing the firmware to Kernel2 and setting the
boot partition to FW2:
mtd write zyxel.bin Kernel2
