consolidate ice and iavf Tx vector paths

This patchset consolidates the ice and iavf vector Tx paths, moving the code to net/intel/common. The iavf code is used as the basis for the move, because it has a superset of the features. When the common code is adopted by the ice driver, it then gains features such as QinQ support and tunneling support.

V3:
* fix variable shadowing issue in patch 15 (ci_txq_vec_capable param)
* update ice.ini with new features

V2:
* fix build when iova not in mbuf
* add extra patch to consolidate the offload flags

Bruce Richardson (15):
net/iavf: remove unnecessary alignment calls net/intel: make Tx context flag common
net/iavf: use separate params for VLAN and QinQ position net/iavf: deduplicate tunnel field fill functions net/intel: define common macros for tunneling bit-shifts net/intel: move iavf descriptor writing functions to common net/intel: use function callback for lldp net/intel: allow building without IOVA in mbuf net/ice: use common descriptor creation functions net/intel: move vector Tx paths to common net/ice: use common AVX Tx functions
net/intel: add common vector Tx fns with context handling net/intel: improve Tx path selection logic net/ice: enable context desc offloads for vector Tx net/intel: consolidate Tx vector offload path checks
