Hi Andreas and Dinh  Thanks for your feedback i will check it.

hmm, I was looking at the code and indeed I have some doubt on
mdio_bus_data management that the patch changes explaining
why the Andreas's box fails and phy_add is not detected.

Keep the sync

Okay Thanks Peppe

Indeed, reverting Gabriel's commit fixes the observed error messages

However, I am unable to ping any hosts on the network now.

hmm, this could be another problem. I wonder if you can
check which recent patch is introducing the problem on ARM64.
For example if this depends on Oct_2015 update.

I've had success reverting drivers/net/ethernet/stmicro/ up to and
including "stmmac: first frame prep at the end of xmit routine", i.e.
top 7 commits.

Andreas, I will check it and let you know asap.

I verified that it's just these two commits that I need to revert:

"stmmac: Fix 'eth0: No PHY found' regression"
"stmmac: first frame prep at the end of xmit routine"

Those in between don't cause conflicts and seem to work okay.

I'm seeing the same issue on the SoCFPGA platform:

libphy: PHY stmmac-0:ffffffff not found
eth0: Could not attach to PHY
stmmac_open: Cannot attach to PHY (error: -19)

If I just revert:

  "stmmac: Fix 'eth0: No PHY found' regression"

then the issue goes away.

Thanks,
Dinh
