Hi Tomeu, Dinh, Andreas
I need a sum and help from you to go ahead on the
tx timeout.
The "stmmac: MDIO fixes" seems to be the candidate to
fix the phy connection and I will send the V2 asap (Andreas' comment).
So, supposing the probe is ok and phy is connected,
I need your input ...
Tomeu: after revering the 0e80bdc9a72d (stmmac: first frame
prep at the end of xmit routine) the network is
not stable and there is a timeout after a while.
The box has 3.50 with normal desc settings.
Dinh: the network is ok, I wonder if you can share a boot
log just to understand if the normal or enhanced
descriptors are used.
Andreas: you are also using 3.50 with normal desc but I have not
clear if just reverting 0e80bdc9a72d commit the
network is ok or you see timeout issues.
In the meantime I am trying to find a box where try normal setup
and I can confirm that enhanced descriptors are ok on my side
Regards
Peppe
