When i use mii-tool too Kick the tranceiver... it comes alive.. i can
ping the eth0 itself

root@X5000LNX:/home/skateman# mii-tool -R eth0
resetting the transceiver...
root@X5000LNX:/home/skateman# ping 192.168.22.44

What PHY driver are you using?

This smells a bit like an RGMII-ID problem.

Hi Andrew,

From another thread[1] on the same topic:

I am not sure what PHY hardware/configuration you are using on the
DS and RDB platforms, but I can confirm that AmigaONE X5000/20
(Cyrus Motherboard with p5020 SoC), has dTSEC 4 and dTSEC 5
wired to two Micrel KSZ9021RN Gigabit Ethernet PHYs, using the
RGMII protocol.
