This patch contains the initial implemenation of a VLAN test suite that ensures the correct functionality of VLAN filtering, stripping, and header insertion on the poll mode driver. VLAN filtering is a useful feature for separating one Ethernet network into multiple logical networks, which enhances network security as it prevents wireless devices from accessing LAN resources. In order to differentiate these packets based on which VLAN they originate from, VLAN tags are inserted in the packet header, and they are either dropped or forwarded based on a VLAN filter list stored on a given port. If a port does not exhibit this behavior, it can compromise the security of the network.
There are four test cases this suite implements: 1. Packet reception when tag is in the filter list and stripping is off 2. Packet reception without tag when tag is in filter list and stripping is on 3. No packet reception when tag is not in the filter list 4. Packet reception with tag when tag insertion is on If these all pass, the poll mode driver is correctly configured to use vlan features with no security concerns.
