Greetings Andrew,
I was mistaken, the Mac address belongs with UMAC,
not the phys. The reason ports are listed here is
because having two separate phy-handles
in one node is not allowed. The layout of the
hardware inside the GXP is unconventional.
There is a description of the layout in the cover-letter,
I see though I need to add a better description.
The internal-phy is connected to the external
phy via SGMII. To use UMAC0 we need to
configure both the internal, and external phy to enable
networking.
Ideally it would be something like this:
umac0: umac@4000 {
compatible = "hpe, gxp-umac";
reg = <0x4000 0x80>;
interrupts = <10>;
interrupt-parent = <&vic0>;
mac-address = [94 18 82 16 04 d8];
ext-phy-handle = <&ext_phy0>;
int-phy-handle = <&int_phy0>;
};
Thanks,
-Nick Hawkins
