This patch set enables RSS/FDIR/cloud filter for
GPT-C and GTP-U.
It depends on Kirill's patch:
http://www.dpdk.org/dev/patchwork/patch/28294/

v2 changes:
 - Enable RSS/FDIR/cloud filter dinamicly by checking profile
 - Add GTPC and GTPU items to distinguish rule for GTP-C or GTP-U
 - Rework FDIR/cloud filter enabling function

Beilei Xing (6):
  net/i40e: support RSS for GTP-C and GTP-U
  ethdev: add GTPC and GTPU items
  net/i40e: finish integration FDIR with generic flow API
  net/i40e: add FDIR support for GTP-C and GTP-U
  net/i40e: add cloud filter parsing function for GTP
  net/i40e: enable cloud filter for GTP-C and GTP-U
