UCC GETH does not work on my MPC8360EA

Hello,

I have a wired problems with my MPC8360EA using Linux 2.6.27-rc6. The
UCC GEHT controller works fine with 100/Full but fails with 1000/Full.
What I see is that the TX done interrupts come (ifconfig's TX packet
counter goes up), but the messages does not show up on the wire. RX
seems to work properly, though.

Any idea what's going wrong? Does someone got it working with 1000/Full?

TIA,

Wolfgang.

This looks like an old problem that RGMII Tx shouldn't use internal
delay while Rx should use.  So try to use 'rgmii-rxid' as
phy-connection-type in device tree.  Also there should have been a fixup
in u-boot for this.  So update to use latest u-boot might fix your
problem.

I do not have problems with U-Boot using 1000/full. The DTS property

  phy-connection-type = "rgmii-rxid"

fixed the problem wuth Linux, indeed, but I realize slow boot over NFS
and sometimes I even get "nfs server not responding" with that setting.

I mean that the latest u-boot can fixup the phy-connection-type
automatically base on the chip revision.
