I've noticed that in most cases when genphy_update_link() is called, the ethernet driver (mt7628-eth in this case) fails with the first ethernet packets. Resulting in a timeout of the first tftp command. Increasing the delay in the link check look from 1 to 50 ms and moving it below the BMSR register read fixes this issue, resulting in a stable ethernet traffic, even after initial link autonogotiation.
