Hi all,
does anyone have working driver for xps_ll_temac unsing sg dma and checksum
offload on rx and tx ??
I use the xlnx kernel with ARCH=powerpc and a device tree generated with the
gen_mhs_devtree under EDK 10.1
I don't know what's wrong but i can't get or send anything even the speed is
only 10 Mb/s !
that's what i get when the kernel starts...

I can see the led blinking on my switch but don't see nothing using wireshak !!!
Finaly, i know the the temac works because i can use it with uboot !!! even
at speed 1000.
