Subject: [PATCH bpf-next v3 06/10] xsk: propagate napi_id to XDP socket Rx path
From: Björn Töpel <bjorn.topel@...el.com>
Add napi_id to the xdp_rxq_info structure, and make sure the XDP
socket pick up the napi_id in the Rx path. The napi_id is used to find
the corresponding NAPI structure for socket busy polling.
