From 8a5f2166a6288ee4b5a393f1ebc8cfb26b0510f0 Mon Sep 17 00:00:00 2001 From: Henrik Austad Date: Tue, 17 Oct 2017 12:10:10 +0200 Subject: [PATCH] net: export netdev_txq_to_tc to allow sch_mqprio to compile as module In commit 32302902ff09 ("mqprio: Reserve last 32 classid values for HW traffic classes and misc IDs") sch_mqprio started using netdev_txq_to_tc to find the correct tc instead of dev->tc_to_txq[] However, when mqprio is compiled as a module, it cannot resolve the symbol, leading to this error: ERROR: "netdev_txq_to_tc" [net/sched/sch_mqprio.ko] undefined! This adds an EXPORT_SYMBOL() since the other user in the kernel (netif_set_xps_queue) is also EXPORT_SYMBOL() (and not _GPL) or in a sysfs-callback.
