Title:
  DHCP server incorrectly handling VLAN tagged packets

Status in isc-dhcp package in Ubuntu:
  Confirmed
Status in Debian:
  Fix Released

Bug description:
  Upon receipt of a VLAN tagged packet, the DHCP server is processing it
  as though it was received without a VLAN tag.

  Steps to reproduce:
  - Send a DHCPDISCOVER packet to the broadcast address with a VLAN tag

  Expected results:
  - None. The DHCP server should ignore this packet.

  Actual results:
  - The DHCP server interprets the packet as though it were received untagged and transmits a response accordingly.

  Comments:
  - I believe this to be an instance of Debian bug #643564
