[Intel-wired-lan] [PATCH v2 0/3] i40e: Support for XDP

[Björn Töpel]

From: Björn Töpel <bjorn.topel at intel.com>

This series adds XDP support for i40e-based NICs.

The first patch adds XDP_RX support, the second XDP_TX support and the
last patch makes it possible to change an XDP program without
rebuilding the rings.

Thanks to Daniel for pointing out that checking against
xdp_adjust_head support has to be done in ndo_xdp.

v2:
  * Fixed kbuild error for PAGE_SIZE >= 8192.
  * Renamed i40e_try_flip_rx_page to i40e_can_reuse_rx_page, which is
    more in line to the other Intel Ethernet drivers (igb/fm10k).
  * Validate xdp_adjust_head support in ndo_xdp/XDP_SETUP_PROG.
