What platform? Linux and FreeBSD both support an 802.1q/VLAN encapsulation
driver. I've used both to run DHCP and they work very well. They both
expose an interface to DHCPd, so there's nothing 'special' as far as DHCPd
is concerned. In Linux there's an option you have to sometimes set that
makes sure the Layer2 Ethernet headers are correct in order to make certain
the DHCPd works. In any case it's not the DHCPd that does the VLAN
interface, it's the host OS.
