bananapi awge0 & dhcpcd issue observed in current-20160702

Hi *!

I am currently observing that dhcpcd does not seem to obtain an ip 
address at boot on awge0.

ifconfig shows status active, but no ip address. Shortly after the 
ifconfig the ip address is optained though.

Doing ifconfig seems to get things unwedged. It looks like dhcpcd does 
not recognize the carrier for awge0 at first (until ifconfig).

Is anybody seeing similar behavior on current-20160702 ?
