Just wonder - what is the major reason double vlan support (also known =
as q-in-q or nested vlan)  is still not included in freebsd. The need =
for this feature is growing parallely with new L3 switches being =
available (cisco, allied telesyn, foundry networks etc...). Enabling =
this in some cases could make freebsd the only solution for backbone =
operators.=20
Brook Davis mentioned q-in-q would make inefficient vlan code even =
worse...but that was some time ago...hope the situation changed nowdays
