It can be used to set the priority bits in a VLAN header, but it doesn’t prioritise traffic in case of contention. Not in the FreeBSD machine anyway. It can help the switch make better prioritisation decisions if it runs into contended interfaces. Also, it’s not possible to prioritise incoming packets. Traffic shaping is in essence the art of throwing away the right packets. It’s done when forwarding between a fast and a slow interface, and always to the packets going from the fast to the slow interface. In the reverse direction there’s no reason to drop packets. All of the packets coming in from a slow interface will fit out the fast interface, so there’s no need to drop any.
