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?
diff --git a/drivers/net/e1000.c b/drivers/net/e1000.c
index 2ba03ed..206884d 100644
--- a/drivers/net/e1000.c

- txp->buffer_addr = cpu_to_le64(virt_to_bus(hw->pdev, nv_packet));

thank you
