Sometimes it takes up to a minute with Gigabit Ethernet to actually ramp up the PHY and get the links trained too. That's usually a thing of the past, but can still happen depending on the hardware. But I'd expect that the kernel driver wouldn't actually set IFF_LOWER_UP on the interface until it has actually successfully negotiated the link... And thus NM wouldn't start DHCP until the device could actually transmit stuff.
