From 0d8300325660f81787892a1c58dc1f9428a67143 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 8 May 2018 19:37:06 -0700 Subject: bpf: xdp: allow offloads to store into rx_queue_index It's fairly easy for offloaded XDP programs to select the RX queue packets go to. We need a way of expressing this in the software. Allow write to the rx_queue_index field of struct xdp_md for device-bound programs. Skip convert_ctx_access callback entirely for offloads.
