I would please like to ask if configuring a device tree/board file with a switch (for example marvell switch) will provide all ports behins the switch as valid interface (ethX) ports in userspace ifconfig command ?

Where in dsa driver the are the ports enabled ? I can't see it in drivers.

But now I think I understand how it works. I do see that mv88e6123_61_65_setup() , do set these bits 0-1 to '1' (00- disabled, 11- forwarding) Yet, I would like to ask one more question about it. I use older kernel (2.6), because these is the Linux from provider chip (TI). I did not find any example how to configure marvell switch in board file, but only in device tree. (we use 88E6176, but any other switch example would help). Is there an example maybe for this which someone can provide ?

TI really only provides 2.6?
