Now that OpenWrt implements a proper fix for the stalled boots on 74kc
boards, the previous workaround can be removed.

It looks like boot hangs on an AC-Mesh for unknown reasons. The last
message seen on the console is:

    [    0.000000] Inode-cache hash table entries: 8192 (order: 3, 32768 bytes, linear)

But interestingly, it seems like enabling AIO somehow works around this
problem. Changing any off the following options seem to have the same
effect at the moment for Linux 5.10.160+5.10.161

    # CONFIG_KERNEL_AIO is not set
    # CONFIG_KERNEL_CGROUPS is not set
    # CONFIG_KERNEL_FANOTIFY is not set
    # CONFIG_KERNEL_FHANDLE is not set
    # CONFIG_KERNEL_IO_URING is not set
    # CONFIG_KERNEL_IPV6_MROUTE is not set
    # CONFIG_KERNEL_IPV6_SEG6_LWTUNNEL is not set
    # CONFIG_KERNEL_IP_MROUTE is not set
    CONFIG_KERNEL_PROC_STRIPPED=y

Just enable CONFIG_AIO until the actual problem was fixed.

Ubiquiti Nanostation Loco M XW was renamed in v2022.1.x, but the alias to the old name was missing, so devices running the old release did not update.

Note: Buffalo has introduced hardware changes without bumping the
revision number. 19.07 did not support the rb-variant so there's no need
to implement a migration for the rb-variant.
Every g300nh supported by Gluon should either be the s-variant or
been flashed wrongly.

Note that it was wrongly marked as device class tiny in
commit 7fd7116e ("targets: add device-class flags") in the past,
the device has 64MB RAM and not 32MB.

Also, the device has no "led-running" assigned in DTS. The device has
three LEDs: "green:vpn", "green:lan" and "green:wlan". The first LED,
"green:vpn", has a "V" icon and was used to show the VPN connection
status in the vendor firmware. This LED will be used via the newly
added "led-boot" fallback in gluon-setup-mode. But will be unused
during normal operation due to the unassigned "led-running" in DTS.

TP-Link TL-WR902AC v1 is a pocket-size, dual-band (AC750), successor of
TL-MR3020 (both devices use very similar enclosure, in same size). New
device is based on Qualcomm QCA9531 v2 + QCA9887. FCC ID: TE7WR902AC.

Specification:

- 650/391/216 MHz (CPU/DDR/AHB)
- 1x 10/100 Mbps Ethernet
- 1x USB 2.0 (GPIO-controlled power)
- 64 MB of RAM (DDR2)
- 8 MB of FLASH
- 2T2R 2.4 GHz (QCA9531)
- 1T1R 5 GHz (QCA9887)
- 5x LED (GPIO-controlled), 2x button, 1x 3-pos switch
- UART pads on PCB (TP1 -> TX, TP2 -> RX, TP3 -> GND, TP4 -> 3V3, jumper
  resitors are missing on TX/RX lines)
- 1x micro USB (for power only)

Flash instructions:

Use "factory" image under vendor GUI.

Recovery instructions:

This device contains tftp recovery mode inside U-Boot. You can use it to
flash OpenWrt (use "factory" image) or vendor firmware.

1. Configure PC with static IP 192.168.0.66/24 and tftp server.
2. Rename "openwrt-ath79-generic-tplink_tl-wr902ac-v1-squashfs-factory.bin"
   to "wr902acv1_un_tp_recovery.bin" and place it in tftp server dir.
3. Connect PC with LAN port, press the reset button, power up the router
   and keep button pressed until WPS LED lights up.
4. Router will download file from server, write it to flash and reboot.

MAC Address summary:
- wlan1 (2.4GHz Wi-Fi): Label MAC
- wlan0 (5GHz Wi-Fi): Offset -1 from label
- eth0 (Wired): Offset +1 from label

Root access over serial line in vendor firmware: root/sohoadmin.

Use the candelatech firmware for the QCA Wave-2 firmware.

The Qualcomm firmware used for the IPQ401x chip in OpenWrt in 22.03
is experiencing heavily degraded performance due to excessive
retransmits when using A-MSDU. Disabling VHT modes or switching to the
candelatech firmware circumvents this issue.

Apply the same to other Wave-2 platforms in order to keep consistency
with upstream.

Wave-1 chips do not support mesh modes with the -ct firmware, so keep
using the QCA firmware in their case.
