Subject: [PATCH net-next 0/4] mvpp2: XDP support

From: Matteo Croce <[email protected]>

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

Hey Ilias,

Could you please review this driver mvpp2 for XDP and page_pool usage?
