[PATCH v2] ethdev: add GTP PSC QFI field

[Dariusz Sosnowski <dsosnowski@nvidia.com>]

This patch introduces the GTP PSC QFI modify field support and adds
the testpmd CLI command support.

An example for copying GTP QFI field using modify_field action:

	modify_field op set
	             dst_type meta
	             src_type gtp_psc_qfi
	             width 8

An example of setting GTP QFI field value to 0x1f using modify_field
action:

	modify_field op set
	             dst_type gtp_psc_qfi
	             src_type value src_value 1f
	             width 8
