[U-Boot] Ethernet i210 (e1000 driver) on tegra K1

[Ivan Mercier]

Hi,

I'm using a ethernet controller intel i210 
(http://www.commell.com.tw/product/Surveillance/MPX-210.htm) on my 
nvidia tegra k1 jetson.

I not an expert with pci, but the only way to make it working in u-boot 
(upstream) is with the workaround below.

E1000 is very common, so finding a critical bug in this driver seems 
weird...
Do you think there is a bug in e1000.c or in tegra pci layer?

      txp->upper.data = 0;



thank you
