[Bug 1167614] [NEW] DHCP server incorrectly handling VLAN tagged packets

[Kevin Otte]

Public bug reported:

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
