[v5,0/3] Tunnel Offload API

  Tunnel Offload API provides hardware independent, unified model
to offload tunneled traffic. Key model elements are:
 - apply matches to both outer and inner packet headers
   during entire offload procedure;
 - restore outer header of partially offloaded packet;
 - model is implemented as a set of helper functions.

 v2:
 * documentation updates
 * MLX5 PMD implementation for tunnel offload
 * testpmd updates for tunnel offload

 v3:
 * documentation updates
 * MLX5 PMD updates
 * testpmd updates

 v4:
 * updated patch: allow negative values in flow rule types

v5:
 * rebase to next-net

32 build fails [1], can you please check?

Also there are a few typos [2].
