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.
Do you have any benchmark numbers? It should help with none XDP
traffic as well. So maybe iperf numbers before and after?

OK, I will add benchmark numbers in the next version.
I will also fix a potential issue with TX buffer type, which is not properly
handled in this v2. It should be set for each buffer, I think (instead of just
being set for the tx channel before initiating xmit).
