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.
