dummynet in 8.1

[Matias]

Hi,

I've read in the release notes that ipfw and dummynet have been improved.

I've wonder if with 8.1 will it be possible to bridge a VLAN Trunk and 
filter VLAN tagged frames (actually, send packets to a dummynet queue 
for traffic shapping).

I've tried this with 8.0 but seems like ipfw does not understand vlan 
tagged frames.

Thanks!
