Hi all,

This patch series adds XDP support for the igc driver. For more context see the
cover letter from v1 in [1]. This v2 addresses the feedback received from the
community (thanks, Maciej Fijalkowski).

The main changes from v1 are:

	* Moved igc_rx_offset() changes to the patch the introduces XDP_PASS
	  action support.
	* Fixed uninitialized variable issue in igc_xdp_run_prog().
	* Changed wrapping code to avoid modulo operation.
	* Removed redundant xdp_rxq_info_unreg_mem_model() call.

A separated patch will be provided to address the comment about double VLAN
tagging in igc_change_mtu().
