Hi,

currently it is possible to configure receive queue assignment using the VLAN
TCI field with arbitrary masks. However, the hardware only supports steering
either by full TCI or the priority (PCP) field. In case a wrong mask is given by
the user the driver will silently convert it into a PCP filter which is not
desired. Therefore, add a check for it.

Patch #1 is a minor thing found along the way.

Changes since v1:

 - Split patches 4 and 5 for -net
 - Rebase to -net
 - Wrap commit message at 75 chars
 - Add Ack from Vinicius
