The first dhcp command consistently fails with a timeout when the lion-rk3368 board is connected to a Zyxel GS1100-24E Gigabit Ethernet switch:
ethernet@ff290000 Waiting for PHY auto negotiation to complete......... TIMEOUT !
Increasing PHY_ANEG_TIMEOUT from the default 4000 to 8000 makes the first dhcp command work reliably.
