This patch series adds AF_XDP support socionext netsec driver
In addition the new dma allocation scheme offers a 10% boost on Rx
pps rate using 64b packets

- patch [1/2]: Use a different allocation scheme for Rx DMA buffers to 
  prepare the driver for AF_XDP support
- patch [2/2]: Add XDP support without zero-copy

test and performance numbers (64b packets):
-------------------------------------------
- Normal SKBs on Rx: ~217kpps
test: pktgen -> intel i210 -> netsec -> XDP_TX/XDP_REDIRECT
- XDP_TX: 320kpps
- XDP_REDIRECT: 320kpps

qemu -> pktgen -> virtio -> ndo_xdp_xmit -> netsec
- ndo_xdp_xmit: Could not send more than 120kpps. Interface forwarded that 
                with success

Changes since v2:
 - Always allocate Rx buffers with XDP_PACKET_HEADROOM
 
 Björn Töpel:
 - Added locking in the Tx queue

 Jesper Dangaard Brouer:
 - Added support for .ndo_xdp_xmit
 - XDP_TX does not flush every packet

Changes since v1:
- patch [2/2]:
 Toshiaki Makita:
 - Added XDP_PACKET_HEADROOM
 - Fixed a bug on XDP_PASS case
 - Using extact for error messaging instead of netdev_warn, when
   trying to setup XDP

Ilias Apalodimas (2):
  net: socionext: different approach on DMA
  net: socionext: add XDP support

This series adds *XDP* support and as a result, the AF_XDP batteries
are included. ;-)

Noted, thanks for cathcing this, i replaced all other AF_XDP -> XDP but seems
like i missed this one!
