This is the status on my side: I am testing on an HW that has the
Enhanced descriptors and all works fine.
On this HW, if I force the driver to use the normal descriptor
layout, I meet problems but using both net.git and net-next.
So I suspect I cannot ply with this HW forcing the normal descriptors.
But! That is helping me to check if, on net-next, the stmmac is
actually programming fine the normal desc case.
I have just found another fix so I kindly ask you to apply the temp
patch attached and let me know.
In details, I have noticed that the OWN bit was not set in the right
I also ask you to give me a log of the kernel where the stmmac was
running fine. I would like to see which configuration it is selected
at runtime by the driver on your box.
From your previous logs (where the stmmac failed), it seems that
the problem is on normal desc but, to be honest, this is the first
case I see a 3.50a with HW capability register and w/o Enhanced
Are you still working on a fix for:
[ 1.196110] libphy: PHY stmmac-0:ffffffff not found
[ 1.200972] eth0: Could not attach to PHY
[ 1.204991] stmmac_open: Cannot attach to PHY (error: -19)
I see the error still there as of linux-next 20160330.
