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"

I only reverted "stmmac: Fix 'eth0: No PHY found' regression". I do have the
patch "stmmac: first frame prep at the end of the xmit routine", but I did not
need to revert that patch.

Hi,

in order to get the onboard network on the Radxa Rock2 to work at all
on today's linux-next, I had to revert both commits:

* "stmmac: Fix 'eth0: No PHY found' regression" for the drivers to
probe and the link to come up, and

* "stmmac: first frame prep at the end of the xmit routine" for the
network interface to work at all.

But a few seconds into the nfsroot boot I start getting:

[    9.136701] systemd[1]: Started Load Kernel Modules.
[   18.116321] nfs: server 10.42.0.1 not responding, still trying

[   18.529456] NETDEV WATCHDOG: eth0 (rk_gmac-dwmac): transmit queue 0 timed out

I'm attaching the full boot log.

Regards,

Tomeu
