Re: [PATCH net] veth: fix queue index used to wake the peer txq in veth_poll

Hello:

This patch was applied to netdev/net.git (main)

veth_poll() derives the index of the peer TX queue to wake from
rq->xdp_rxq.queue_index. That field is only initialized by
xdp_rxq_info_reg() in veth_enable_xdp_range(), which runs only when an
XDP program is attached. On the plain GRO/NAPI path
(veth_napi_enable_range()) xdp_rxq_info_reg() is never called, so
queue_index stays 0 for every queue, as priv->rq is zero-allocated. The
same happens once an XDP program is detached while GRO stays enabled,
since xdp_rxq_info_unreg() clears the struct again.
