6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Roger Quadros <rogerq@xxxxxxxxxx>
[ Upstream commit 624d3291484f9cada10660f820db926c0bce7741 ]
We are not using ndev->stats for rx_packets and rx_bytes anymore.
Instead, we use per CPU stats which are collated in
am65_cpsw_nuss_ndo_get_stats().
Fix RX statistics for XDP_TX and XDP_REDIRECT cases.
Fixes: 8acacc40f733 ("net: ethernet: ti: am65-cpsw: Add minimal XDP support")
