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.

do you have this patch "stmmac: first frame prep at the end of xmit 
routine" ? Or you just reverted
   "stmmac: Fix 'eth0: No PHY found' regression"

maybe we can sum:

   "stmmac: Fix 'eth0: No PHY found' regression"
            that is introducing a problem when a box
            has a transceiver

  "stmmac: first frame prep at the end of xmit routine"
            That is breaking the tx path on arm64

I will check both patches on my side and let you know

peppe

Thanks,
Dinh
