Mux the MT7530 switch's phy0/4 to the SoC's gmac1 on devices where RGMII2
pins are available. This achieves 2 Gbps total bandwidth to the CPU using
the second RGMII.
The ports called "wan" are muxed where possible. On a minority of devices,
this is not possible. Those cases:
mt7621_ampedwireless_ally-r1900k.dts: lan3
mt7621_ubnt_edgerouter-x.dts: eth0
mt7621_gnubee_gb-pc1.dts: ethblue
mt7621_linksys_re6500.dts: lan1
mt7621_netgear_wac104.dts: lan4
mt7621_tplink_eap235-wall-v1.dts: lan0
mt7621_tplink_eap615-wall-v1.dts: lan0
mt7621_ubnt_usw-flex.dts: lan1
The "wan" port is just what the vendor designated on the board/plastic
chasis of the device. On a technical level, there is no difference between
a lan and wan port on MT7621AT, MT7621DAT and MT7621ST SoCs. Prefer
connecting to WAN via the port described above for these devices to benefit
the feature brought with this patch.
mt7621_d-team_newifi-d2.dts cannot benefit this feature, although it looks
like it should, because the rgmii2 pins are wired to unused components.
Tested on a range of devices documented on the GitHub PR.

ipTIME A6004NS-M is a 2.4/5GHz band AC1900 router, based on MediaTek MT7621A.
Specifications:
- SoC: MediaTek MT7621A (880MHz, Duel-Core)
- RAM: DDR3 256MB
- Flash: SPI NOR 16MB (Winbond W25Q128BV)
- WiFi: MediaTek MT7615E (2.4GHz, 5GHz)
- Ethernet: MediaTek MT7530 (WAN x1, LAN x4, SoC built-in Estimated)
- USB: USB 3.0 x1
- UART: [3.3V, TX, RX, GND] (57600 8N1)
Installation via web interface:
1. Flash initramfs image using OEM's Firmware Update page.
2. Connect to OpenWrt with an SSH connection to `192.168.1.1`.
3. Perform sysupgrade with sysupgrade image.
Revert to stock firmware:
1. Flash stock firmware via OEM's Recovery mode
How to use OEM's Recovery mode:
1. Power on the device and connect the shell through UART.
2. Connect to the shell and press the `t` key on the keyboard.
3. Set fixed IP with `192.168.0.2` with subnet mask `255.255.255.0`
4. Flash image via TFTP to `192.168.0.1`
Additional Notes:
1. The higher the 5Ghz Frequency, the lower the stability. It is recommended to use less than 5.775Ghz.
2. If the 5Ghz frequency is too high, 5Ghz may not work.
3. A6ns-M use shared dtsi file of A6004NS-M. (reference: /mt7621_iptime_a6004ns-m.dtsi).
