net: ethernet: ti: am65-cpsw: Add minimal XDP support
This patch adds XDP (eXpress Data Path) support to TI AM65 CPSW
Ethernet driver. The following features are implemented:
- NETDEV_XDP_ACT_BASIC (XDP_PASS, XDP_TX, XDP_DROP, XDP_ABORTED)
- NETDEV_XDP_ACT_REDIRECT (XDP_REDIRECT)
- NETDEV_XDP_ACT_NDO_XMIT (ndo_xdp_xmit callback)
The page pool memory model is used to get better performance.
Below are benchmark results obtained for the receiver with iperf3 default
parameters:
- Without page pool: 495 Mbits/sec
- With page pool: 605 Mbits/sec (actually 610 Mbits/sec, with a 5 Mbits/sec
loss due to extra processing in the hot path to handle XDP).
