Asus AX55 Duplex change


New Around Here
Hello all, I am new here and to the RT-AX55 Firmware Version:

I need to force the duplex of a lan port.
I understand there is no GUI option for this, if you happen to know one please let me know.

What I also know is there is no robocfg on the cli.

You can see the physical interfaces are attached to the br0 here

[email protected]:/tmp/home/root# brctl show
bridge name     bridge id               STP enabled     interfaces
br0             8000.fc3497d00688       yes             eth1

I am able to use ethctl to get the bridge control but am unsure of how to change the duplex from here, no command seems to be working.

[email protected]:/tmp/home/root# ethctl br0 media-type 1000FD port 3
invalid interface name br0
  media-type : Set/Get media type
  ethctl <interface> media-type [option] [port <sub_port#> ]
    [option]: auto - auto select
              10000FD - 10Gb, Full Duplex
              5000FD - 5Gb, Full Duplex
              2500FD - 2.5Gb, Full Duplex
              1000FD - 1000Mb, Full Duplex
              1000HD - 1000Mb, Half Duplex
              100FD - 100Mb, Full Duplex
              100HD - 100Mb, Half Duplex
              10FD  - 10Mb,  Full Duplex
              10HD  - 10Mb,  Half Duplex
    [port <sub_port#>]: required if <interface> has Crossbar or Trunk port underneath

If anyone knows a better way to do this, or the solution, I would be immensely grateful.
