Since commit 2bd82484bb4c ("xps: fix xps for stacked devices"),
skb->napi_id shares storage with sender_cpu. RX tracepoints using
net_dev_rx_verbose_template read skb->napi_id directly and can therefore
report sender_cpu values as if they were NAPI IDs.
For example, on the loopback path this can report 1 as napi_id, where 1
So I think veth_forward_skb->__netif_rx could be affected as well?
Yes. Just in case, I've confirmed the same behavior in the veth path.
The mentioned loopback path is just a single example of possibly
affected paths.
Thanks,
