Hi,
Since recent (last 6 months) snapshots (also latest rc2) I'm having a weird issue with my travel router. (it has MT7981)
For some reason, it doesn't recognize the link if I boot the device with cable plugged and I cannot even manually do autoneg via ethtool after then. But if I boot the device unplugged, ethtool allows me to set autoneg, then I can establish the link once I plug the cable.
Then I checked the issues, .
I'm just trying to understand what could cause this, thanks!
What device you have?
ubus call system board
ethtool wan
ethtool -i wan
mii-tool -v wan # (and some other port, just to see whether "good" and "bad" port has same phy circuit)
ubus output:

}
}
ethtool -i eth0: (this time booted without plugging cable, I'm able to set autoneg this way.)
root@tr3000:~# ethtool eth0

On this step if I do ethtool -s eth0 autoneg on speed 1000 duplex full, it detects link.
So, next one ethtool -i eth0:

And bonus: booted with cable plugged in and here's the weird thing:

And autoneg does not do anything, link remains down.
And here comes the dmesg output (with cable plugged before booting):

For some reason:
[ 13.766379] mtk_soc_eth 15100000.ethernet eth0: configuring for phy/2500base-x link mode
I don't understand why it's trying to set the link to 2.5G, switch ports are 1G. Tried with several different switches (mt6000, ax3600), issue remains the same.
eth0 is dsa parent, it has fixed mii link to a switch. 1gbps for anything up to 7621 and 2.5gbps from 7622 onwards.
I was asking mii-tool against (if you have 2.5gbps or) any lanX port with real life ethernet connector.
Check
ip link
lan1@eth5 would be form of DSA ports, where I ask to run mii-tool and ethtool against lan1 part.
here's the ip link output:
root@tr3000:~# ip link

link/ether 82:af:ca:29:76:25 brd ff:ff:ff:ff:ff:ff
In case necessary:
root@tr3000:~# cat /etc/config/network
config interface 'loopback'
option device 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fd60:1ba8:b093::/48'
config device
option name 'br-lan'
option type 'bridge'
list ports 'eth1'
config interface 'lan'
option device 'br-lan'
option proto 'static'
option ipaddr '192.168.152.1'
option netmask '255.255.255.0'
option ip6assign '60'
config interface 'wan'
option device 'eth0'
option proto 'dhcp'
config interface 'wan6'
option device 'eth0'
option proto 'dhcpv6'
One step further:
I've reversed the wan and lan, magically it started working 
@therpa What exactly do you mean by “reversed the wan and lan” to get it working?
changed ports of interfaces, eth1 for WAN eth0 for LAN
Hmmm, I tried that as well, but no luck on the Ruijie X60 Pro.
Problem is related, as we don't know why that fixed it for you, it's hard to diagnose.
Thanks for the clarification!
