Moment, DHCP is not arp packet.
and ARP is not DHCP.

DHCP is always IP addressed /check via tcpdump/
so you can mark these addresses with tc without any problems.

ARP packets are low level packets of ethernet interconnectivity.
They will work always, unless your LAN is overloaded or somebody will do
nasty things like /arp poisoning/.
The only way you can increase your network performance for arp packets is
enabling broadcast storm control in layer-2 devices.
Some limmitations of arp-settings in linux /proc filesystem (gc_thresh_...
etc)
You can neither set static arp from Server side /and client side too (more
complex)/
