Subject: [PATCH v2 net-next 0/8] add XDP support to mvneta driver

Add XDP support to mvneta driver for devices that rely on software
buffer management. Supported verdicts are:
- XDP_DROP
- XDP_PASS
- XDP_REDIRECT
- XDP_TX
Moreover set ndo_xdp_xmit net_device_ops function pointer in order to support
redirecting from other device (e.g. virtio-net).
Convert mvneta driver to page_pool API.
This series is based on previous work done by Jesper and Ilias.

Changes since v1:
- sync dma buffers before refilling hw queues
- fix stats accounting

Changes since RFC:
- implement XDP_TX
- make tx pending buffer list agnostic
- code refactoring
- check if device is running in mvneta_xdp_setup

Lorenzo Bianconi (8):
  net: mvneta: introduce mvneta_update_stats routine
  net: mvneta: introduce page pool API for sw buffer manager
  net: mvneta: rely on build_skb in mvneta_rx_swbm poll routine
  net: mvneta: sync dma buffers before refilling hw queues
  net: mvneta: add basic XDP support
  net: mvneta: move header prefetch in mvneta_swbm_rx_frame
  net: mvneta: make tx buffer array agnostic
  net: mvneta: add XDP_TX support
