From bb54dcca3fb5696c493690e3922eca9567791b34 Mon Sep 17 00:00:00 2001 From: Gilberto Bertin Date: Fri, 10 Apr 2020 18:20:59 +0200 Subject: [PATCH] net: tun: record RX queue in skb before do_xdp_generic() [ Upstream commit 3fe260e00cd0bf0be853c48fcc1e19853df615bb ] This allows netif_receive_generic_xdp() to correctly determine the RX queue from which the skb is coming, so that the context passed to the XDP program will contain the correct RX queue index.
