Subject: [PATCH v2.55] datapath: Add basic MPLS support to kernel

Hi Pravin, Hi Jesse, Hi All,

I have updated this patch so that:

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

  I have done this by white-listing the following:
  - ETH_P_IP (0x0800)
  - ETH_P_ARP (0x0806)
  - ETH_P_RARP (0x0835)
  - ETH_P_IPV6 (0x86DD)

  Previously it was done by blacklisting the following:
  - ETH_P_8021Q (0x8100)
  - ETH_P_8021AD (0x88A8)
  - ETH_P_QINQ1 (0x0x9100)
  - ETH_P_QINQ2 (0x0x9200)
  - ETH_P_QINQ3 (0x0x9300)

  Although the whitelist probably wants to be expanded
  it seems to me to be a more conservative and safer
  way to guard against unknown tag ordering.

to aid review this patch is available in git at:
