cable-test support

Hello.

Which of those routers support cable-test ( https://wiki.mikrotik.com/wiki/Manual:Interface/Ethernet#Detect_Cable_Problems ):

  1. hEX RB750Gr3 (MT7621)
  2. RB951Ui-2HnD (Atheros8227)
  3. RB951G-2HnD (Atheros8327)
    ?

RB951Ui-2HnD and RB951G-2HnD support cable-test feature, hEX RB750Gr3 does not.

MT7621A don’t support “cable test”… so… maybe you will remove this “black hole button” from interface on hEX and hEX S?
