This series adds AF_XDP zero coppy support to am65-cpsw driver.

Tests were performed on AM62x-sk with xdpsock application [1].

A clear improvement is seen in 64 byte packets on Transmit (txonly) and receive (rxdrop). 1500 byte test seems to be limited by line rate (1G link) so no improvement seen there in packet rate. A test on higher speed link (or PHY-less setup) might be worthwile.

There is some issue during l2fwd with 64 byte packets and benchmark results show 0. This issue needs to be debugged further. A 512 byte l2fwd test result has been added to compare instead.

It appears that the drivers/net/ethernet/ti/am65-* files do not fall under any MAINTAINERS entry. Please add one or extend the existing CPSW entry as the first patch of the series.
