Connect the NIC to managed L2 switch. Configure connection as a trunk
carrying some vlans. Configure remaining L2 switch ports as untagged
and assign them do appropriate vlans. Functionally you'll have Linux
router with more NICs (groups of untagged switch ports will be
equivalent to one linux NIC). On linux system you'll have separate
interfaces like eth0.1 eth0.2 and so on. This can significantly ease
task of shaping and routing your traffic the way you want it.

Another option is using IFB/IMQ for shaping traffic, but such setup
won't be too straightforward and bug-prune.
