Subject: [PATCH v2.54] datapath: Add basic MPLS support to kernel

Hi Jesse, Hi All,

As per the suggestion made by Ben in relation to this patch
I have updated it so that:

* The datapath rejects push MPLS actions in the presence of VLAN tags.

  I have done this by blacklisting the following:
  - ETH_P_8021Q (0x8100)
  - ETH_P_8021AD (0x88A8)
  - ETH_P_QINQ1 (0x0x9100)
  - ETH_P_QINQ2 (0x0x9200)
  - ETH_P_QINQ3 (0x0x9300)

  But perhaps a safer option would be to whitelist only ethertypes
  we are completely comfortable with. Starting with:
  - ETH_P_IP (0x0800)
  - ETH_P_ARP (0x0806)
  - ETH_P_IPV6 (0x86DD)
