Description

On ESXi, incoming VLAN traffic fails to reach the related VLAN interface if PCP is set to anything else than the default value (0); it stops at the parent interface.

The problem and setup is almost identical to issue #2613, except it only occurs when incoming PCP is not default.
It occurs on my regular setup (inbound IPtv traffic on WAN with PCP 4) and also on a test setup between two pfSense over a dedicated (virtual) LAN.

So if inbound VLAN packets have default PCP (0) it's fine and traffic goes through to the actual VLAN interface.
But if PCP differs from 0, packets stops being forwarded to the VLAN interface, and are only visible on the parent.

The host is ESXi 5.5 with E1000 or VMXNET3 virtual adapters (no difference).
The hardware is a Dell Poweredge 2900 II with integrated BMC5708 NICs
Tested with pfSense 2.1.4 and 2.2-ALPHA.
