Fixing emulated ofdpa in cpqd switches. Due to cpqd bugs in dealing with Vlans and MPLS labels simultaneously,
we cannot emulate correct behavior in the same driver. This checkin separates the emulation, with one
driver meant for MPLS with untagged packets, and the other meant for untagged/tagged VLAN packets without MPLS.
