[U-Boot] i.MX6Q SabreLite: Ethernet does not work at Gigabit speed

Hi,

I just realized that I cannot download files on a Gitabit Ethernet network. I'm getting timeouts:

MX6QSABRELITE U-Boot > boot Using FEC device TFTP from server 172.16.0.1; our IP address is 172.16.0.100 Filename 'wolf/uImage-mx6q-mainline'. Load address: 0x10800000 Loading: error frame: 0x4fd76ca0 0x00000804 T error frame: 0x4fd77f00 0x00000804

Before I start digging, is this a known issue?

Wolfgang.
