  From: Wenxuan Wu <wenxuanx.wu@intel.com>

Due to the change of struct rte_gtp_psc_generic_hdr, kernel driver can
not handle gtp_psc properly, we introduce a new structure to fix this
gap between kernel driver and struct rte_gtp_psc_generic_hdr.

Fixes: d5eb3e600d9e ("net/iavf: support flow director basic rule")
