It enables 'extended tag' for i40e devices only during its port
initialization, which is key for 40G performance. It also deprecates
the similar in igb_uio, and eal lib.

v2:
 - Changed the type of return value of i40e_enable_extended_tag() to 'void'.
 - Fixed the compile warnings.
 - Kept the sys files as they were, and added ABI change announcement for them.
 - Moved high performance part of i40e from 'GSG' to a new for .nics'.

Helin Zhang (3):
  i40e: enable extended tag
  eal: remove pci config of extended tag
  igb_uio: deprecate sys files
