If you're asking how to support vlans in FreeBSD, add lines like these
to rc.conf:

cloned_interfaces="vlan0"
ifconfig_bce1="inet 0.0.0.0"
ifconfig_vlan0="vlan 250 vlandev bce1"
ifconfig_vlan0_alias0="inet 161.53.72.23 netmask 255.255.255.0"

This has worked for me in 6.2 and 6.3. Hardware VLAN filtering is
supported in both 6.x and 7.x (at least in bce driver; look for
VLAN_HWTAGGING flag in ifconfig).

I've asked that question about a week ago on network developers mailing
list and the answer was that it could be done but it's not yet
implemented (i.e. using VLANs in any way effectively disables TSO).
