       set_flag [vlan-device] 0 | 1
              When 1, ethernet header  reorders  are  turned  on.
              Dumping the device will appear as a common ethernet
              device without vlans. When 0(default) however, eth­
              ernet  headers  are not reordered, which results in
              vlan tagged packets when dumping the  device.  Usu­
              ally the default gives no problems, but some packet
              filtering programs might have problems with it.


Podle mne se tam pise, ze kdyz pak tcpdumpem posloucham na drate, tak
vidim normalni pakety bez vlanu.
