This question could arguably be posted on both networking.stackexchange and unix.stackexchange. I'll start here.

I have a freeBSD (pfsense 2.1) server running as a router on google fiber.

In order to get above 10 Mbps I need to enable egress filtering on the wan port
(aka 802.1p, traffic priority, Class of Service, CoS, vlan pcp ).

Running ifconfig, I can see that the vlanpcp is set to 0.

How do I change the vlanpcp from 0 to 3 ? 

ifconfig
...
re0_vlan2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    options=3<RXCSUM,TXCSUM>
    ether 00:1c:c0:d5:e0:e2
    inet 23.255.241.45 netmask 0xfffff800 broadcast 23.255.247.255
    inet6 fe80::21c:c0ff:fed5:e0e2%re0_vlan2 prefixlen 64 scopeid 0x8
    nd6 options=3<PERFORMNUD,ACCEPT_RTADV>
    media: Ethernet autoselect (1000baseT <full-duplex>)
    status: active
    vlan: 2 vlanpcp: 0 parent interface: re0

It looks link on linux this can be done with vconfig, however freebsd doesn't use vconfig.

For reference, I am using these instructions for setting up the vlans.

FreeBSD is not like Linux. This is particularly true regarding network configuration: "everything" is in ifconfig. A simple man ifconfig will confirm you that.

So to change the value of vlanpcp for you re0_vlan2:

ifconfig re0_vlan2 vlanpcp 3
