Add XDP support to mvpp2. This series converts the driver to the
page_pool API for RX buffer management, and adds native XDP support.

These are the performance numbers, as measured by Sven:

SKB fwd page pool:
Rx bps     390.38 Mbps
Rx pps     762.46 Kpps

XDP fwd:
Rx bps     1.39 Gbps
Rx pps     2.72 Mpps

XDP Drop:
eth0: 12.9 Mpps
eth1: 4.1 Mpps

Matteo Croce (4):
  mvpp2: refactor BM pool init percpu code
  mvpp2: use page_pool allocator
  mvpp2: add basic XDP support
  mvpp2: XDP TX support
