Did you capture and compare network traffic on the different interfaces
(physical, VLAN, bridge) ? Did you check the kernel and dhclient logs ?

Did you try different DHCP clients (pump, dhcpcd, udhcpc...) ?

Different hardware, different drivers ? Offload optimizations
enabled/disabled (see ethtool) ?
