Thank you for CC'ing me on this series. Sorry, but I have been M.I.A.
for the past couple of months due to some health issues, which caused a
backlog at work that I had to power through. I haven't been able to
monitor the mailing list for stmmac patches.
I tested v1 last night and just picked up v2. Here are my observations
and logs (phylink logs are enabled). I haven't had time to debug the
issues, but they are not seen on the net-next tree. One thing that I
remember from our last discussion is the need to test with comma
detection enabled; I will test that next.
Tested on the QCS9100 Ride R3 board with 2X AQR115C PHYs. I have one
more board that I can test next week (IQ8275, which has a single
QCA8081 PHY, but that is limited to 2.5G because the PHY switches its
mode according to the speed).
1. Boot up at 2.5G: Continous TX timeouts keep issuing a reset,
resulting in a broken data path.

2. Boot up at 1G: link state is flapping + the same TX timeout issue as
above. Also, a warning due to qcom-ethqos toggling ANE. For the link
state flapping issue, the MAC/IOMACRO configuration looks fine to me, do
we need to handle something in the PHY?

That's all I have right now. I will try to test out with comma detection
enabled and share the results in a day or so.

Thank you for CC'ing me on this series. Sorry, but I have been M.I.A.
for the past couple of months due to some health issues, which caused a
backlog at work that I had to power through. I haven't been able to
monitor the mailing list for stmmac patches.
I tested v1 last night and just picked up v2. Here are my observations
and logs (phylink logs are enabled). I haven't had time to debug the
issues, but they are not seen on the net-next tree. One thing that I
remember from our last discussion is the need to test with comma
detection enabled; I will test that next.
Tested on the QCS9100 Ride R3 board with 2X AQR115C PHYs. I have one
more board that I can test next week (IQ8275, which has a single
QCA8081 PHY, but that is limited to 2.5G because the PHY switches its
mode according to the speed).
1. Boot up at 2.5G: Continous TX timeouts keep issuing a reset,
resulting in a broken data path.

2. Boot up at 1G: link state is flapping + the same TX timeout issue as
above. Also, a warning due to qcom-ethqos toggling ANE. For the link
state flapping issue, the MAC/IOMACRO configuration looks fine to me, do
we need to handle something in the PHY?
